Answer:

y= -5x+12

Step-by-step explanation:

slope int form ; y=mx+b

that is the only option in that form.

Answer:

the equation is y = 5x + 12

Step-by-step explanation:

The equation of line is 10x - 2y=-2

Write this equation in slope intercept form of line y = mx + b

[tex]10x-2y=-2\\\\2y=10x+2\\\\y=5x+1[/tex]

Therefore, the slope of the line is m = 5

Now, we know that parallel lines have same slope.

Hence, slope of the required line is also 5.

Thus, the equation of line is in the form y = 5x + b

Now, use the point (0,12) to find b

12= 5(0) + b

b = 12

Hence, the equation is y = 5x + 12

Write it out as an equation:

3 < 1/3P

Rewrite so P is on the left side:

1/3P >3

Multiply each side by 3:

1/3P x 3 > 3 x 3

Simplify:

P > 9

Answer:

Up down and side to side on the graph

Step-by-step explanation:

If a is 1, since it is positive the parabola moves up. If a is -1, since it is negative the parabola moves down. (not sure about side to side because I can't back that one up but I'm 100% sure about up and down)

When a is between 0 and 1, the parabola gets wider.

A parabola is a mathematical curve that is defined by a point and a line. The point is known as the focus, and the line is called the directrix. The parabola has the property that all points on it are equidistant from the focus and the directrix.

Here,

When a is negative, the parabola flips 180°.

When |a| is less than 1, the parabola opens wider.

When |a| is greater than 1, the parabola opens more narrow.

When a is between 0 and 1, the parabola gets wider, when it is greater than 1, it gets narrower, and when it is less than 0 it is reflected across the x-axis.

Therefore, when a is between 0 and 1, the parabola gets wider.

Answer:

B and C

Step-by-step explanation:

There are 3 conditions for the difference of squares.

The correct answer is B and C

Final answer:

Binomials that are a difference of squares have the form a² - b² and can be factored into (a + b)(a - b), where both terms are perfect squares. Examples include x² - 9 and 4y² - 25.

Explanation:

To determine which binomials are a difference of squares, we look for expressions in the form of a2 - b2. A difference of squares can be factored into (a + b)(a - b), where a and b are any expressions. It is essential that both terms be perfect squares and that they are subtracted from one another.

For example, x2 - 9 is a difference of squares as it can be factored into (x + 3)(x - 3), where both x2 and 9 are perfect squares. Another example could be 4y2 - 25, which factors to (2y + 5)(2y - 5). Keep in mind that if the sign is not subtraction, or if either term is not a perfect square, the binomial does not represent a difference of squares. The correct choice of examples, factoring process, and the nature of perfect squares are essential to identify differences of squares accurately.

Answer:

10 cm

Step-by-step explanation:

If the length of a rectangle is equal to triple the width, the width of the rectangle is 10 cm if the perimeter is 80 centimeters.​

L = 3w

P = 80

Formula: a = l × w

8W = 80 cm

W = 80 / 8 = 10 cm

Therefore, the width of the rectangle is 10 centimeters.

The width of the rectangle is found to be 10 centimeters, obtained by solving the equation created based on the fact that the perimeter of a rectangle is 2(length + width) and the given data that length is thrice the width and perimeter is 80 cm.

To figure out the width of the rectangle, we first need to understand the relationship between the length and width, and how they relate to the perimeter. The length of the rectangle is triple the width. Let's define the width as 'w'. Therefore, the length would be '3w'.

The formula for the perimeter of a rectangle is 2(length + width).

Given that the perimeter is 80 centimeters, we can set up the equation 2(3w + w) = 80. Simplifying this gives 8w = 80. To find the width 'w', we divide both sides of the equation by 8, giving us w = 10 centimeters.

Therefore, the width of the rectangle is 10 centimeters.

The integers are -5 , -6 ⇒ answer C

Step-by-step explanation:

* Lets explain the meaning of consecutive numbers

- Consecutive numbers are numbers that follow each other in order.

-  They have a difference of 1 between every two numbers

- Consider that the smaller of two consecutive integer is n, then the

  larger one will be n + 1

* In the problem

∵ The larger of the two consecutive integers is 7 greater than twice

  the smaller

- That means the larger one is 7 plus twice the smaller

∵ The smaller one is n

∵ The larger one is n + 1

∴ n + 1 = 2(n) + 7

∴ n + 1 = 2n + 7

- Subtract n from both sides

∴ 1 = n + 7

- Subtract 7 from both sides

∴ -6 = n

∴ The smaller number is -6

∵ The greater number is n + 1

∴ The greater number = -6 + 1 = -5

* The integers are -6 , -5

Answer:

C; The left end goes up; the right end goes down

Step-by-step explanation:

If you expand the function, you end up with a polynomial with a negative coefficient and it has an odd power. According to polynomial behaviors of a function that is odd negative, the graph will rise to the left (y → ∞ and x → -∞) and falls to the right (y → -∞ and x → ∞).

ANSWER

C. The left end goes up; the right end goes down.

EXPLANATION

The given function is

[tex]f(x) = - 2( {x - 2)}^{5} [/tex]

We analyze the end behavior of this function using the leading term.

The leading term of this function is:

[tex] - 2 {x}^{5} [/tex]

Since the degree(5) is odd and the leading coefficient (-2) is negative, the graph rises on the left and falls on the right.

In other words, the left end of the graph goes up and the right end goes down.

The correct option is C.

Answer:

The correct answer is first option

x = 12, y = 10

Step-by-step explanation:

From the figure we can see that a triangle ADC, and EB is parallel to side DC.

To find the value pf x

From the given figure we get,

<ABC = <BCD  [ corresponding angles are equal]

3x + 9 = 4x - 3

4x - 3x = 9 + 3

x = 12

To find the value of y

<ABE and <EBC are linear pairs.

Therefore, <ABE + <EBC = 180

(3x + 9)  + (14y - 5) = 180

(3 * 12 + 9) + 14y - 5 = 180

45 + 14y - 5 = 180

14y = 180 -40

14y = 140

y = 140/14 = 10

y = 10

Therefore x = 12 and y = 10

Answer:

The radius is [tex]\frac{\sqrt{74}}{2}[/tex].

The center is (5/2 , 9/2).

Step-by-step explanation:

The radius is half the diameter.  We aren't given the length of the diameter but we are given endpoints to one of them.

So let's find the length of that diameter using the distance formula.

The distance formula is

[tex]d=\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}[/tex].

I just do big x minus small x or big y minus small y.

Anyways the points are (-1,7) and (6,2).

The x distance is 6-(-1)=7.

The y distance is 7-2=5.

So we have this using the distance formula so far:

[tex]d=\sqrt{(6-(-1))^2{(7-2)^2}[/tex]

[tex]d=\sqrt{7^2+5^2}[/tex]

[tex]d=\sqrt{49+25}[/tex]

[tex]d=\sqrt{74}[/tex]

So the radius is half that much because that was the distance between the endpoints of a diameter.

So the radius is [tex]\frac{\sqrt{74}}{2}[/tex].

Now the center of a circle will lie on the midpoint of a diameter, any given diameter.

We have the endpoints of one, so we just need to use midpoint formula.

Midpoint formula says the midpoint is (average of x, average y).

Midpoint formula: [tex](\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex].

So average of x's is (-1+6)/2=5/2.

The average of y's is (7+2)/2=9/2.

So the midpoint of the diameter or the center of the circle is at (5/2 , 9/2).

The answer is A.75°

The sum of all the angles of a triangle is 180°

75+35+x = 180.

x = 180-75-35

x = 75

A triangle is a three-sided polygon, which has three vertices. The three sides are connected with each other end to end at a point, which forms the angles of the triangle.

The sum of all three angles of the triangle is equal to 180 degrees.

The angles of a triangle always add up to 1800 degrees because one exterior angle of the triangle is equal to the sum of the other two angles in the triangle. When all the angles are added up, the sum obtained should be 180 degrees.

Step-by-step explanation:

(g - h)(x) = 4x - 4 - (x - 5)  ( Note we put the x - 5 in parentheses)

= 4x - 4 - x + 5

=  3x + 1.

(g.h)(x) = (4x - 4)(x - 5)

so (g.h)(1) = (4(1) - 4)(1 - 5)

= 0 * -4

= 0.

The product of the functions will be (g·h)(x) = 4x² – 24x + 20. At x = 1, the product of the functions is zero.

A statement, principle, or policy that creates the link between two variables is known as a function.

The functions are given below.

g(x) = 4x – 4

h(x) = x – 5

Then the sum of the functions will be

(g + h)(x) = (4x – 4) + (x – 5)

(g + h)(x) = 4x – 4 + x – 5

(g + h)(x) = 5x – 9

Then the difference in the functions will be

(g – h)(x) = (4x – 4) – (x – 5)

(g – h)(x) = 4x – 4 – x + 5

(g – h)(x) = 3x + 1

Then the product of the functions will be

(g·h)(x) = (4x – 4)(x – 5)

(g·h)(x) = 4x² – 4x – 20x + 20

(g·h)(x) = 4x² – 24x + 20

At x = 1, then we have

(g·h)(x) = 4(1)² – 24(1) + 20

(g·h)(x) = 4 - 24 + 20

[tex]13x+3y=11[/tex] (standard form)

Let me know if you prefer another form.

Step-by-step explanation:

The slope of a line can be found using [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] provided you are given two points on the line.

We are.

Now you can use that formula.  But I really love to just line up the points vertically then subtract them vertically then put 2nd difference over 1st difference.

 (4/5  ,  1/5)

-( 1/2  ,  3/2)

-----------------

3/10          -13/10

2nd/1st = [tex]\frac{\frac{-13}{10}}{\frac{3}{10}}=\frac{-13}{3}[/tex] is our slope.

So the following is point-slope form for a linear equaiton:

[tex]y-y_1=m(x-x_1) \text{ where } m \text{ is slope and } (x_1,y_1) \text{ is a point on the line }[/tex]    

Plug in a point [tex](x_1,y_1)=(\frac{1}{2},\frac{3}{2}) \text{ and } m=\frac{-13}{3}[/tex].

This gives:

[tex]y-\frac{3}{2}=\frac{-13}{3}(x-\frac{1}{2})[/tex]

I'm going to distribute:

[tex]y-\frac{3}{2}=\frac{-13}{3}x-\frac{-13}{6}[/tex]

Now I don't like these fractions so I'm going to multiply both sides by the least common multiply of 2,3, and 6 which is 6:

[tex]6y-9=-26x+13[/tex]

Add 26x on both sides:

[tex]26x+6y-9=13[/tex]

Add 9 on both sides:

[tex]26x+6y=22[/tex] This is actually standard form of a line.

It can be simplified though.

Divide both sides by 2:

Answer:

[tex]\large\boxed{y=-\dfrac{13}{3}x+\dfrac{11}{3}}-\bold{slope\ intercept\ form}\\\boxed{13x+3y=11}-\bold{standard\ form}[/tex]

Step-by-step explanation:

The slope-intercept form of an equation of a line:

[tex]y=mx+b[/tex]

m - slope

b - y-intercept

The formula of a slope:

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

We have two points

[tex]\left(\dfrac{4}{5},\ \dfrac{1}{5}\right),\ \left(\dfrac{1}{2},\ \dfrac{3}{2}\right)[/tex]

Convert fractions to the decimals

(divide the numerator by the denominator) :

[tex]\dfrac{4}{5}=0.8,\ \dfrac{1}{5}=0.2,\ \dfrac{1}{2}=0.5,\ \dfrac{3}{2}=1.5[/tex]

[tex]\left(\dfrac{4}{5},\ \dfrac{1}{5}\right)=(0.8,\ 0.2)\\\\\left(\dfrac{1}{2},\ \dfrac{3}{2}\right)=(0.5,\ 1.5)[/tex]

Calculate the slope:

[tex]m=\dfrac{1.5-0.2}{0.5-0.8}=\dfrac{1.3}{-0.3}=-\dfrac{13}{3}[/tex]

Put the value of slope and the coordinates of the first point to the equation of a line:

[tex]0.2=-\dfrac{13}{3}(0.8)+b[/tex]      multiply both sides by 3

[tex]0.6=(-13)(0.8)+3b[/tex]

[tex]0.6=-10.4+3b[/tex]           add 10.4 to both sides

[tex]11=3b[/tex]           divide both sides by 3

[tex]\dfrac{11}{3}=b\to b=\dfrac{11}{3}[/tex]

Finally:

[tex]y=-\dfrac{13}{3}x+\dfrac{11}{3}[/tex] - slope-intercept form

Convert to the standard form (Ax + By = C):

[tex]y=-\dfrac{13}{3}x+\dfrac{11}{3}[/tex]      multiply both sides by 3

[tex]3y=-13x+11[/tex]          add 13x to both sides

[tex]13x+3y=11[/tex] - standard form

Answer:

American Bison

Step-by-step explanation:

First find out how many feet the bison runs in an hour.

To find that out you have to multiply 3520 by 60 minutes because there are 60 minutes in an hour.

So 3520*60 = 211,200 feet

Then you have to convert 211,200 feet into miles and since there are 5,280 feet in an a mile you have to divide.

So 211,200 divided by 5,280 = 40

So the American Bison runs 40 miles per hour which is faster than the White Tailed Deer who only runs 30 miles per hour.

So the answer is the American Bison.
