Step-by-step explanation:

Verify each statement

case A) Clayton could use the relationship (x,y)→ (y,x) to find the points of the image

The statement is true

we know that

The rule of the reflection of a point across the line y=x is equal to

(x,y)→ (y,x)

case B) Clayton could negate both the x and y values in the points to find the points of the image

The statement is false

case C) C’ will remain in the same location as C because it is on the line of reflection

The statement is true

If a point is on the line of reflection (y=x), then the point remain in the same location because the x and y coordinates are equal

case D) C’ will move because all points move in a reflection

The statement is false

Because C' is on the line of reflection (y=x), then the point remain in the same location

case E) The image and the pre-image will be congruent triangles

The statement is true

Because the reflection not change the length sides of the triangle or the measure of its internal angles. Reflection changes only the orientation of the figure

case F) The image and pre-image will not have the same orientation because reflections flip figures

The statement is true

Because in a reflection across the line y=x, the x coordinate of the pre-image becomes the y-coordinate of the image and the y-coordinate of the pre-image becomes the x-coordinate of the image

Answer:

It is a solution

Step-by-step explanation:

Check and see if (0,0) satisfies both inequalities.

The first inequality is:

[tex]y \geqslant {x}^{2} + x - 4 [/tex]

When we put x=0, and y=0, we get:

[tex]0\geqslant {0}^{2} + 0 - 4[/tex]

[tex] \implies0\geqslant- 4[/tex]

This part is true.

The second inequality is:

[tex]y \leqslant {x}^{2} + 2 x + 1[/tex]

We put x=0 and y=0 to get:

[tex]0 \leqslant {0}^{2} + 2 (0) + 1[/tex]

[tex]0 \leqslant 1[/tex]

This part is also true.

Since the (0,0) not satisfy both, inequalities, it is a solution.

Answer:

4x - 3y = 5

Step-by-step explanation:

The equation of a line in standard form is

Ax + By = C ( A is a positive integer and B, C are integers )

First obtain the equation in point- slope form

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 1, - 3) and (x₂, y₂ ) = (2, 1)

m = [tex]\frac{1+3}{2+1}[/tex] = [tex]\frac{4}{3}[/tex]

Using (a, b) = (2, 1), then

y - 1 = [tex]\frac{4}{3}[/tex] (x - 2) ← in point- slope form

Multiply both sides by 3

3y - 3 = 4(x - 2) ← distribute and rearrange

3y - 3 = 4x - 8 ( add 8 to both sides )

3y + 5 = 4x ( subtract 3y from both sides )

5 = 4x - 3y, so

4x - 3y = 5 ← in standard form

Sure, let's find the equation of the line that passes through the points (-1, -3) and (2, 1) step-by-step.
1. First, calculate the slope (m) of the line using the formula:
  \[
  m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{1 - (-3)}{2 - (-1)}
  \]
  \[
  m = \frac{1 + 3}{2 + 1} = \frac{4}{3}
  \]
2. The slope-intercept form of a line equation is \( y = mx + b \), where \( m \) is the slope and \( b \) is the y-intercept.
  We already found the slope \( m = \frac{4}{3} \), so we just need to find \( b \).
  Using the first point (-1, -3), plug the values into the slope-intercept form:
  \[
  -3 = \frac{4}{3}(-1) + b
  \]
  Calculate \( b \):
  \[
  -3 = -\frac{4}{3} + b
  \]
  Add \( \frac{4}{3} \) to both sides:
  \[
  b = -3 + \frac{4}{3}
  \]
  \[
  b = -\frac{9}{3} + \frac{4}{3}
  \]
  \[
  b = -\frac{5}{3}
  \]
3. Now we have \( y = \frac{4}{3}x - \frac{5}{3} \) in slope-intercept form.
4. Next, we will convert this to standard form, which is \( Ax + By = C \), where \( A \), \( B \), and \( C \) are integers, and \( A \) is positive.
  Multiply both sides of the slope-intercept equation by 3, the common denominator, to eliminate fractions:
  \[
  3y = 4x - 5
  \]
5. Rewriting in standard form, we move the \( x \)-term to the left side:
  \[
  -4x + 3y = -5
  \]
6. In standard form, \( A \) should be positive. If we multiply the entire equation by -1, we will make \( A \) positive:
  \[
  4x - 3y = 5
  \]
7. This is already simplified since the greatest common divisor (GCD) of 4, -3, and 5 is 1. Thus, the coefficients are already in their simplest integer values.
The final equation for the line in standard form is:
\[ 4x - 3y = 5 \]

Answer:

24

Step-by-step explanation:

The area of the given figure ABCD with respective coordinates is

24 square units.

The area of a quadrilateral is nothing but the region enclosed by the sides of the quadrilateral.

Given the coordinates of the quadrilateral as; A(−4, 1), B(2, 1), C(2, −5), and D(−4, −3).

By inspection, we see that the y coordinates of A and B are the same. Thus, their length will be the difference of their x coordinates. Thus;

AB = 2 - (-4)

AB = 6

Similarly, B and C have same x coordinates. Thus;

BC = -5 - 1 = -6

A and D have same x coordinate and as such;

AD = -3 - 1 = -4

AB and BC are perpendicular to each other because of opposite signs of same Number and since AD has a different length, then we can say that the figure ABCD is a rectangle.

Thus;

Area of figure = 6 × 4 = 24 square units.

The area of the given figure ABCD with respective coordinates is

24 square units.

Answer:

f(x) = (x-1)² + 3

Step-by-step explanation:

f(x)  = 4+x²-2x   or f(x)  = x²- 2x + 4   -----> eq 1

consider the top-most choice

f(x) = (x-1)² + 3 = x² + 2·x·(-1) + 1²  +  3

f(x) = x² - 2x+ 1  +  3

f(x) = x² - 2x+ 4  -----> compare this with eq 1 above (they match!)

hence f(x) = (x-1)² + 3 is the answer

Step-by-step explanation:

We are given that a bike has 16 spokes which are spaced evenly apart.

We are to find the measure of angles of rotation.

Spoke is basically the rod which comes from the center of the tire, connecting it to the round surface.

Since the total measure of angles for a circle is 360° and 16 spokes are places evenly, so each angle of rotation = [tex]\frac{360}{16}[/tex] = 22.5°

Answer:

-3/4 degree Fahrenheit

Step-by-step explanation:

The temperature is decreasing by 3/16 each day

We write that as -3/16

There are 4 days in which we are measuring

Total temperature change = rate of change* number of days

                                            =-3/16 * 4

                                            = -12/16

We can simplify this by dividing the top and bottom by 4

-12/4 =3

16/4 =4

                                         =12/16 = -3/4

Answer:

-3/4 degree Fahrenheit

No graph has been plotted, but the question is answerable either way and I'll be happy to help you. In this problem, we have the following inequality:

[tex]x-y-2\geq 0[/tex]

Before we focus on getting the shaded region, let's graph the equation of the line:

[tex]x-y-2=0[/tex]

So let's write this equation in slope intercept form [tex]y=mx+6[/tex]:

STEP 1: Write the original equation.

[tex]x-y-2=0[/tex]

STEP 2: Subtract -x from both sides.

[tex]x-y-2-x=0-x \\ \\ \\ Group \ like \ terms \ on \ the \ left \ side: \\ \\ (x-x) - y-2=-x \\ \\ The \ x's \ cancel \ out \ on \ the \ left: \\ \\ -y-2=-x[/tex]

STEP 3: Add 2 to both sides.

[tex]-y-2+2=-x+2 \\ \\ -y=-x+2[/tex]

STEP 4: Multiply both sides by -1.

[tex](-1)(-y)=(-1)(-x+2) \\ \\ y=x-2[/tex]

So, [tex]m=1[/tex] and [tex]b=-2[/tex]. The graph of this line passes through these points:

[tex]If \ x=0 \ then: \\ \\ y=x-2 \therefore y=(0)-2 \therefore y=-2 \\ \\ Passes \ through \ (0,-2) \\ \\ \\ If \ y=0 \ then: \\ \\ y=x-2 \therefore 0=x-2 \therefore x=2 \\ \\ Passes \ through \ (2,0)[/tex]

By plotting this line, we get the line shown in the first figure below. To know whether the shaded region is either above or below the graph, let's take point (0,0) to test this, so from the inequality:

[tex]x-y-2\geq 0 \\ \\ Let \ x=y=0 \\ \\ 0-0-2\geq 0 \\ \\ -2\geq 0 \ False![/tex]

Since this statement is false, then the conclusion is that the region doesn't include the origin, so the shaded region is below the graph as indicated in the second figure below. The inequality includes the symbol ≥ so this means points on the line are included in the region and the line is continuous.

Answer:

75 cubic centimeters

Step-by-step explanation:

Volume of a cone is the area of the base times a third of the height.

The base is a circle.

The formula for the area of a circle is [tex]\pi \cdot r^2[/tex].

We are given that we want to use [tex]3.14[/tex] for [tex]\pi[/tex] and

r=(diameter)/2=6/2=3 cm.

So the area of the base is [tex]3.14 \cdot 3^2=28.26[/tex].

Now the height of the cone is 8 cm.

A third of the height is 8/3 cm.

So we want to compute area of base times a third of the height.

Let's do that:

[tex]\frac{8}{3} \cdot 28.26[/tex]

75.36 cubic centimeters

To the nearest cubic centimeters this is 75

To calculate the volume of a cone, we use the formula for the volume of a cone, which is:
\[ V = \frac{1}{3} \pi r^2 h \]
Where:
- \( V \) is the volume of the cone
- \( \pi \) is the constant Pi (approximated as 3.14)
- \( r \) is the radius of the cone's base
- \( h \) is the height of the cone
Given that the diameter of the cone is 6 cm, we find the radius by dividing the diameter by 2:
\[ r = \frac{diameter}{2} = \frac{6 cm}{2} = 3 cm \]
Now we have the radius and the height (which is given as 8 cm), we can substitute these values into the formula:
\[ V = \frac{1}{3} \pi r^2 h = \frac{1}{3} \times 3.14 \times (3 cm)^2 \times 8 cm \]
First, square the radius:
\[ (3 cm)^2 = 9 cm^2 \]
Now, perform the multiplication:
\[ V = \frac{1}{3} \times 3.14 \times 9 cm^2 \times 8 cm \]
\[ V = 3.14 \times 3 cm^2 \times 8 cm \]
\[ V = 9.42 cm^2 \times 8 cm \]
\[ V = 75.36 cm^3 \]
Finally, you want to round the volume to the nearest cubic centimeter. Since \( 75.36 \) is already a decimal to the nearest hundredth and has no fractional part in cubic centimeters, we simply round it to the nearest whole number:
\[ V \approx 75 \]
So, the volume of the cone is approximately \( 75 \) cubic centimeters.

Answer:

Miles he drove on highway = 180 miles

Miles he drove in the city = 217 miles

Step-by-step explanation:

Lets assume that gallon used on highway = x

Miles driven on highway = y

(I) 36 miles per gallon on the highway.

36x = y    equation 1

(II) 31 miles per gallon in the city.He recently drove 397 miles on 12 gallons of gasoline

31(12-x)= 397-y    equation 2

372-31x= 397-y

Combine the constants:

-31x= 397-372-y

y-31x = 25

Now substitute the value of equation 1 in equation 2

y-31x=25

36x-31x=25

5x=25

Now divide both sides by 5

5x/5=25/5

x=5

Now substitute the value x=5 in equation 1

36x=y

36(5)=y

180= y

Now subtract the miles driven on highway from recently drove miles to get the miles driven in the city.

397-y = 389 - 180

= 217

Therefore,

Miles he drove on highway = 180 miles

Miles he drove in the city = 217 miles ....

Julio drove 0 miles on the highway and 2856 miles in the city.

To find out how many miles Julio drove on the highway and in the city, we can set up a system of equations. Let x represent the number of miles driven on the highway and y represent the number of miles driven in the city. We know that the total distance driven is 397 miles and the total amount of gas used is 12 gallons. Using the given miles per gallon ratings, we can set up the following equations:

x + y = 397

36x + 31y = 12

From the first equation, we can isolate x:

x = 397 - y

Substituting this value of x into the second equation, we can solve for y:

36(397 - y) + 31y = 12

14292 - 36y + 31y = 12

-5y = -14280

y = 2856

Now we can substitute the value of y back into the first equation to find x:

x + 2856 = 397

x = 397 - 2856

x = -2459

However, since we cannot have negative miles, we know that Julio did not drive any miles on the highway.

Therefore, Julio drove 0 miles on the highway and 2856 miles in the city.

Answer:

No. It is a constant function.

Step-by-step explanation:

The function f(x) = e^2 is not an exponential functional. Rather, it is a constant function. The reason for this is that in f(x) = e^2, there is no x involved on the right hand side of the equation. The approximate value of e is 2.718281, and the approximate value of 2.718281^2 is 7.389051. This means that f(x) = e^2 = 7.389051. It is important to note that for any value of x, the value of the function remains fixed. This is because the function does not involve the variable x in it. The graph of the function will be a line parallel to the x-axis, and the y-intercept will be 7.389051. For all the lines parallel to x-axis, the value of the function remains the same irrespective of the value of x. Also, the derivative of the function with respect to x is 0, which means that the value of the function is unaffected by the change in the value of x!!!

To find the equation that describes the area, A, of a rectangle in terms of x, we use the formula for the area of a rectangle, which is length times width. Given that the length is x + 2 and the width is x - 5, the equation for the area A in terms of x is A = (x + 2)(x - 5).

To express A as a polynomial, we can expand this equation:

A = x(x - 5) + 2(x - 5)

A = x² - 5x + 2x - 10

A = x² - 3x - 10

Therefore, the equation that describes the area of the rectangle in terms of x is A = x² - 3x - 10.

Answer:

x = 40 deg

Step-by-step explanation:

Given that the line at the base of the triangle is a continuous straight line,

x + (4x-20) = 180 degrees

x + 4x  - 20 = 180

5x = 180 + 20

5x = 200

x = 40 deg

Answer:

100 degrees (first choice)

Step-by-step explanation:

So we can actually find the degree measure of arc KI because there is a theorem that says this twice the angle IJK.

75(2)=150 is the degree measure of arc KI.

So a full rotation around a circle is 360 degrees.

This means the following equation should hold:

m(arc)KJ+m(arc)IJ+m(arc)IK=360

Inserting the values given for the arc measures we know:

110         +m(arc)IJ+    150    =360

Add 110 and 150:

260     +m(arc)IJ                   =360

Subtract 260 on both sides:

             m(arc)IJ                   =100

So m(arc)IJ is 100 degrees.

Answer:

0.08

Step-by-step explanation:

A standard deck of 52 cards has four aces.

The sample space is:

n(S) = 52

Let A be the event that an ace is drawn from the deck.

Then,

n(A) = 4

So,

[tex]P(A) = \frac{n(A)}{n(S)}\\ =\frac{4}{52} \\=0.0769[/tex]

Rounding off to the nearest hundredth will give us:

0.08 ..

The theoretical probability of drawing an ace from a standard deck of 52 cards is 0.08. The calculation is based on dividing the number of aces (4) by the total number of cards (52).

The theoretical probability of an event occurring is calculated by dividing the number of ways an event can occur by the total number of possible outcomes. In this scenario, the question is asking about the theoretical probability of drawing an ace from a standard deck of 52 cards.

In a standard deck of cards, there are 4 aces. So, the number of ways the event 'drawing an ace' can occur is 4. The total number of possible outcomes, which is the total number of cards in the deck, is 52. Therefore, the probability of drawing an ace, P(Ace), is calculated as follows:

P(ace) = Number of aces in the deck / Total number of cards

P(ace) = 4 / 52

When you simplify this fraction or convert it into decimal form (rounded to the nearest hundredths), it gives:

P(ace) = 0.08

So, the theoretical probability of drawing an ace from a deck of 52 cards is 0.08.

Answer:

y = (x - [tex]\frac{1}{2}[/tex] )² - [tex]\frac{25}{4}[/tex]

Step-by-step explanation:

Given

y = (x + 2)(x - 3) ← expand factors

  = x² - x - 6

Use the method of completing the square

add/ subtract ( half the coefficient of the x- term )² to x² - x

y = x² + 2(- [tex]\frac{1}{2}[/tex]) x + [tex]\frac{1}{4}[/tex] - [tex]\frac{1}{4}[/tex] - 6

  = (x - [tex]\frac{1}{2}[/tex] )² - [tex]\frac{25}{4}[/tex]

Answer:

m=4

Step-by-step explanation:

11m - 15 -5m= 9

Combine like terms

6m -15 =9

Add 15 to each side

6m - 15+15 = 9+15

6m = 24

Divide each side by 6

6m/6 =24/6

m = 4

Answer:

see explanation

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

To calculate m use the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

3

Using (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (- 3, 6)

m = [tex]\frac{6-0}{-3-0}[/tex] = [tex]\frac{6}{-3}[/tex] = - 2

Since the line passes through the origin (0, 0) then y- intercept is 0

y = - 2x ← equation of line

4

let (x₁, y₁ ) = (6, 0) and (x₂, y₂ ) = (0, 3)

m = [tex]\frac{3-0}{0-6}[/tex] = [tex]\frac{3}{-6}[/tex] = - [tex]\frac{1}{2}[/tex]

note the line crosses the y- axis at (0, 3) ⇒ c = 3

y = - [tex]\frac{1}{2}[/tex] x + 3 ← equation of line

5

let (x₁, y₁ ) = (0, 3) and (x₂, y₂ ) = (-2, - 3)

m = [tex]\frac{-3-3}{-2-0}[/tex] = [tex]\frac{-6}{-2}[/tex] = 3

note the line crosses the y- axis at (0, 3) ⇒ c = 3

y = 3x + 3 ← equation of line

Answer:

ASA postulate

Step-by-step explanation:

The sum of the measures of interior angles of triangle is always 180°, so

∠LRT=180°-∠RTL-∠RLT=180°-∠2-∠4;

∠KST=180°-∠STK-∠SKT=180°-∠1-∠3.

Since

∠1≅∠2 and ∠3≅∠4, we have that ∠LRT ≅ ∠KST.

The ASA (Angle-Side-Angle) postulate states that if two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the triangles are congruent. (The included side is the side between the vertices of the two angles.)

In your case:

Triangles TKS and TLR are congruent by ASA postulate.
