How can I put -2-3=5/4(-2*(2)) into slope intercept form

Answer:

see explanation

Step-by-step explanation:

The equation of a line in point- slope form is

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 ) = (- 2, - 3) and (x₂, y₂ ) = (- 7, 4)

m = [tex]\frac{4+3}{-7+2}[/tex] = [tex]\frac{7}{-5}[/tex] = - [tex]\frac{7}{5}[/tex]

We can use either of the 2 points for (a, b)

Using (a, b) = (- 7, 4), then

y - 4 = -[tex]\frac{7}{5}[/tex](x - (- 7)), that is

y - 4 = - [tex]\frac{7}{5}[/tex](x + 7) ← in point- slope form

Answer:

x = 3 and x = 7

Step-by-step explanation:

Equate the product of the factors to zero, that is

(x - 3)(x - 7) = 0

Equate each factor to zero and solve for x

x - 3 = 0 ⇒ x = 3

x - 7 = 0 ⇒ x = 7

Final answer:

To find the values of x that make a polynomial equal to zero, set each factor equal to zero and solve for x. The values of x that would make the polynomial equal to zero are x = 3, and x = 7.

Explanation:

To find the values of x that make a polynomial equal to zero, you need to set each factor equal to zero and solve for x.

Set x-3=0 and solve for x to get x=3.

Set x-7=0 and solve for x to get x=7.

Therefore, the values of x that would make the polynomial equal to zero are x = 3 and x = 7.

Answer:

(-2,0)

Step-by-step explanation:

To find the midpoint, we need to average our x's and then average our y's.

Our x's are -7 and 3. We average them together like so (-7+3)/2=-4/2=-2.

Our y's are 3 and -3. We average them together like so (3+-3)/2=0/2=0.

So the midpoint is

(average of x's , average of y's).

Our mudpoint is (-2,0).

the answer is 12 days

Step-by-step explanation:

3×4=12

Answer:

8*6 + 12*h ≥144

Step-by-step explanation:

8 dollars at the movie theater

12 dollars at the restaurant

scheduled 6 hours at the movie theater

need to make at least 144 dollars

The money he makes is the hours times the rate

rate * hours at movie theater + rate *hours at restaurant

This must be greater than or equal to 144

Let h be the hours at the movie theater

8*6 + 12*h ≥144

Answer:

3y-x= -6

4y-x=44 ....

Step-by-step explanation:

Let y= 1/3x-2

Let y= 1/4x+11

Now we are required to arrange them in standard form.

So,

y= 1/3x-2

Combine the variable terms:

-1/3x+y=-2

Multiply both sides by 3

3(-1/3x+y)=3* -2

-x+3y= -6

3y-x= -6 ---------equation 1

y= 1/4x+11

Combine the variable terms:

-1/4x+y = 11

Multiply both sides by 4

4(-1/4x+y) = 4*11

-x+4y=44

4y-x=44 -----------------equation 2

Therefore the system of equations is:

3y-x= -6

4y-x=44 ....

Answer: Hello there!

we have that "one thirdx − 2 = one fourthx + 11"

this means  (1/3)x - 2 = (1/4)x + 11

now, we also can write this as:

(1/3)x - 2 = y = (1/4)x + 11

and now we have a system of equations:

(1/3)x - 2 = y

(1/4)x + 11 = y

or

(1/4)x - y = -11

(1/3)x - y = 2

Answer:

The correct answer is C. 2.

Step-by-step explanation:

To solve this problem, we should begin with the second step and work backwards in order to find the unknown value.  If given the equation -15x + 30 = 25, we should factor out a -15 to simplify.  This method is shown below.

-15x + 30 = 25

-15(x-2) = 25

We know this is correct because if we redistribute the -15 through the parentheses using the distributive property, we would get our original equation again.  In other words, this answer is confirmed by the fact that -15 * -2 equals positive 30.

However, we need to look closely at the question that is asked.  The box that we must fill in is already preceded by a negative sign, thus the correct answer is C. 2.

We can check our work by replacing the box with the number 2, getting -15(x-2) + 30 = 25, which was the equation we got earlier.

Hope this helps!

Answer:

22,338 is the smallest number that is divisible by both 306 and 657. In other words, 22,338 is the least common multiple of 306 and 657.

Step-by-step explanation:

The question is asking for the smallest number that is divisible by 306 and 657. That number in question is also known as the least common multiple of 306 and 657.

Neither 306 nor 657 is prime; the two numbers themselves are made of prime factors. For the number in question to be divisible by both 306 and 657, it needs to include the factors of both 306 and 657. However, for this number to be as small as possible, it needs to contain only the necessary factors and nothing else.

To find the factors required for this number, start by finding all the prime factors of the two divisors.

[tex]\begin{aligned}306&=2 \times 153\\ &= 2\times 3 \times 51\\ &= 2 \times 3 \times 3 \times 17 \\ &= 2 \times 3^{2} \times 17\end{aligned}[/tex].

In other words, the prime factors of 306 are:

Similarly,

[tex]\begin{aligned}657&= 3 \times 219\\ & = 3 \times 3 \times 73\\&=3^{2}\times 73 \end{aligned}[/tex].

The prime factors of 657 are:

[tex]\begin{array}{l||l|l||l}\text{Factor}& 306 & 657 & \text{New Number}\\\cline{1-4} \\[-1.0em]2 &\text{1 Occurrence}& \text{0 Occurrence} & \text{1 Occurrence}\\3 &\text{2 Occurrence} & \text{2 Occurrence}& \text{2 Occurrence}\\ 17 &\text{1 Occurrence}& \text{0 Occurrence} & \text{1 Occurrence}\\73 &\text{0 Occurrence}& \text{1 Occurrence} & \text{1 Occurrence}\end{array}[/tex].

The number in question shall contain at least

As a result, that number shall be equal to [tex]2 \times 3^{2}\times 17 \times 73 = 22338[/tex].

Answer:

22/9

Step-by-step explanation:

The slope of a line can be found by using the slope formula

[tex]\frac{y_2-y_1}{x_2-x_1} \text{ where we have points } (x_1,y_1) \text{ and } (x_2,y_2) \text{ on the line }[/tex].

Or what I like to do is line up the points and subtract vertically, then put 2nd difference over 1st difference. Like so:

 ( 10  , 25)

- (  1  ,    3)

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

9         22

So the slope is 22/9.

You could have done it the other way too. That is:

 (1  ,  3)

-(10 , 25)

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

-9    -22

So the slope is -22/-9 or just 22/9.

Answer:

The slope of a trend line is:

[tex]m=\frac{22}{9}[/tex]

Step-by-step explanation:

The slope m of a line is calculated using the following formula:

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

For any pair of points [tex](x_1, y_1),\ (x_2, y_2)[/tex] that belong to the line

In this case the points are (1,3) and (10,25)

Therefore the slope is:

[tex]m=\frac{25-3}{10-1}[/tex]

[tex]m=\frac{22}{9}[/tex]

Answer:

[tex]314.2cm^3[/tex]

Step-by-step explanation:

We use the formula below to find the volume:

[tex]\pi r^2\frac{h}{3}[/tex]

Note:

Simplify:

[tex]\pi 5^2\frac{12}{3}[/tex]

Solve the exponent first, then multiply the fraction:

[tex]\pi 5^2\frac{12}{3} \\\\ 5^2 = 25\\\\ 12/3 = 4\\\\ 25 * 4 = 100\\\\ 100\pi = 314.159[/tex]

Round:

314.15 -> 314.2

Our answer would be [tex]314.2cm^3[/tex]

Answer:

[tex]A=76.44\ units^{2}[/tex]

Step-by-step explanation:

To find the approximate area of the circle, calculate the area of one sector and then multiply by 16

Remember that

The area of a triangle (one sector) is equal to

[tex]A=\frac{1}{2}(b)(h)[/tex]

therefore

The approximate area of the circle is equal to

[tex]A=(16)\frac{1}{2}(1.95)(4.9)[/tex]

[tex]A=76.44\ units^{2}[/tex]

Answer:

D.76.44 square units

Step-by-step explanation:

We are given that

Base of one sector=b=1.95 units

Height of sector=h=4.9 units

Total number of sectors=16

Area of one sector is equal to area of triangle (approximately)

Area of sector=[tex]\frac{1}{2}bh[/tex]

Using the formula

Area of one sector=[tex]\frac{1}{2}(1.95)(4.9)=4.7775[/tex] square units

Area of circle A=[tex]16\times [/tex]area of sector

Area of circle A=[tex]16\times 4.7775=76.44[/tex] square units

Hence,option D is true.

Answer:

add 1/4 to each side

Step-by-step explanation:

x^2+x=11

We take the coefficient of the x term

1

Then divide it by 2

1/2

Then square it

(1/2) ^2 = 1/4

Add this to both sides of the equation

x^2 + x + 1/4 = 11+1/4

(x+1/2)^2 = 11 1/4

Answer:

0.25.

Step-by-step explanation:

x^2 + x = 11

(x + 0.5)^2 - 0.25 = 11

(x + 0.5)^2 - 0.25 + 0.25 = 11 + 0.25

(x + 0.5)^2 = 11.25.

Answer:

So the other x-intercept we are looking for is (2.29 , 0).

Step-by-step explanation:

The equation for a parabola in vertex form is

[tex]y=a(x-h)^2+k[/tex] where (h,k) is the vertex.

So we are given (h,k)=(1,5) so let's plug that in.  This gives us the following equation for our parabola:

[tex]y=a(x-1)^2+5[/tex].

Now we need to find [tex]a[/tex]. Let's find [tex]a[/tex] by using another point (x,y) given.  We are given that (0,2) is on our parabola. So when x is 0, y is 2.

This gives us the equation:

[tex]2=a(0-1)^2+5[/tex]

[tex]2=a(-1)^2+5[/tex]

[tex]2=a(1)+5[/tex]

[tex]2=a+5[/tex]

[tex]2-5=a[/tex]

[tex]-3=a[/tex]

So our parabola in vertex form looks like this:

[tex]y=-3(x-1)^2+5[/tex]

Now we are asked to find the x-intercepts.

You can find the x-intercepts by setting y equal to 0 and solving for x.

So let's do that:

[tex]0=-3(x-1)^2+5[/tex]

Subtract 5 on both sides:

[tex]-5=-3(x-1)^2[/tex]

Divide both sides by -3:

[tex]\frac{5}{3}=(x-1)^2[/tex]

Take the square root of both sides:

[tex]\pm \sqrt{\frac{5}{3}}=x-1[/tex]

Add 1 on both sides:

[tex]\pm \sqrt{\frac{5}{3}}+1=x[/tex]

So the two solutions in exact form are

[tex]x=\sqrt{\frac{5}{3}}+1 \text{ or } -\sqrt{\frac{5}{3}}+1[/tex]

Putting both into calculator (separately) gives:

[tex]x \approx 2.29 \text{ or } -0.29[/tex]

So the other x-intercept we are looking for is (2.29 , 0).

Answer:

mass

Step-by-step explanation:

From the universal law of gravity

[tex]F=G\frac{Mm}{r^2}[/tex]

Where

G = Gravitational constant = 6.674×10⁻¹¹ m³/kg⋅s²

M = Mass of Earth = 5.972×10²⁴ kg

r = Radius of Earth = 6.371×10⁶ m

[tex]\\\Rightarrow ma=G\frac{Mm}{r^2}\\\Rightarrow a=G\frac{M}{r^2}\\\Rightarrow a=6.674\times 10^{-11}\frac{5.972\times 10^{24}}{(6.371\times 10^6)^2}\\\Rightarrow a=9.81\ m/s^2[/tex]

So the force of gravity acting on the mass of an object is

W = m×9.81

∴ Weight of an object is the product of mass and acceleration due to gravity

Answer:

see explanation

Step-by-step explanation:

Given that y varies inversely as x then the equation relating them is

y = [tex]\frac{k}{x}[/tex] ← k is the constant of variation

To find k use the condition x = 2.5 when y = 100

k = yx = 100 × 2.5 = 250

y = [tex]\frac{250}{x}[/tex] ← equation of variation

The constant of variation (k) in the inverse relationship equation (y = k/x) can be determined by multiplying the x and y values provided. In this case, k = 250. Therefore, the equation of variation would be y = 250 / x.

Given the inverse relationship where y varies inversely with x, it follows the general equation of y = k/x. This relationship is provided by the constant of variation (k). It can be determined by multiplying the given x and y values.

In this case, x = 2.5 when y = 100. We substitute these into our inverse relationship equation, yielding 100 = k/2.5. By multiplying both sides by 2.5, we are able to find that k = 250. Therefore, the equation of variation would be y = 250/x.

Answer:

The order pair of point Q' is (-21/4 , -7/2)

Step-by-step explanation:

* Lets explain the dilation

- A dilation is a transformation that changes the size of a figure.  

- The figure can become larger or smaller, but the shape of the

 figure does not change.  

- The scale factor, measures how much the image will be larger

 or smaller  

- If the scale factor greater than 1, then the image will be larger

- If the scale factor between 0 and 1, then the image will be smaller

- The center of dilation is a fixed point in the plane about which all

 points are expanded or contracted

* Lets solve the problem

- The pentagon OPQRS is dilated by a scale factor 7/4

- The center of dilation is the origin

- The image of the pentagon after the dilation is O'P'Q'R'S'

∵ The coordinates of the vertices of the pentagon OPQRS are

  O (-1 , 2) , P (-5 , 3) , Q (-3 , -2) , R (2 , 1) , S (2 , 5)

- To find the image of each point after the dilation multiply each

  coordinates of the points by the scale factor of dilation

∵ The scale factor is 7/4

∵ The coordinates of point Q are (-3 , -2)

∴ The image of point Q after dilation is (-3 × 7/4 , -2 × 7/4)

∴ The image of point Q after dilation is (-21/4 , -7/2)

∵ Q' is the image of Q

∴ Q' = (-21/4 , -7/2)

* The order pair of point Q' is (-21/4 , -7/2)

Step-by-step explanation:

[tex]\left \{ {{5x+2y=-8} \atop {x+4y=2}} \right.[/tex]

I'll be solving this system of equations using the elimination method since the x and y values are neatly lined up.

I want to get a pair of x's or y's that cancel out, and it looks like the easiest way to start would be by multiplying the first equation by -2 (the y's will cancel).

I chose to multiply the first equation by -2 instead of multiplying the second equation by 5 because -2 is a smaller number and easier to multiply by.

[tex]-2\times(5x+2y=-8)[/tex]

Distribute -2 inside the parentheses. Now you've got:

[tex]\left \{ {{-10x-4y=16} \atop {x+4y=2}} \right.[/tex]

Add up the equations from top to bottom.

-10x plus x is -9x, the -4y and 4y cancel out, and 16 plus 2 is 18. Make this one single equation.

[tex]-9x=18[/tex]

Divide both sides by -9.

[tex]x=-2[/tex]

Substitute this value of x into the second equation (less to do with the x since it has no coefficient which means no multiplying).

[tex](-2)+4y=2[/tex]

Add 2 to both sides.

[tex]4y=4[/tex]

Divide both sides by 4.

[tex]y=1[/tex]

The final answer is [tex]x=-2, ~y=1[/tex].

C. positively skewed

Step-by-step explanation:

If a data set has more extremely large data values, the distribution is said to be positively skewed.

Have a great day!

A data set with more extremely large data values is said to be skewed right or positively skewed. This describes a distribution where the tail on the right side is extended due to a few high extreme values.

If a data set has more extremely large data values, the distribution is said to be skewed right or positively skewed. This occurs because the tail of the distribution on the right-hand side is longer or more drawn out compared to the left-hand side.

In a right-skewed distribution, the mean is typically larger than the median, and the mode lies to the left of the median. This asymmetry indicates a larger number of lower values and a few extreme higher values in the data set. For example, if we have a data set with the histogram showing a longer tail on the right, it suggests there are some very large values stretching the scale, resulting in a skewed right distribution.

Answer:

The translation is right 4 units and up 4 units

Step-by-step explanation:

we know that

The rule of the translation of the point V to V' is equal to

(x,y) ----> (x+4,y+4)

That means ----> The translation is right 4 units and up 4 units

Verify

V(-2,3) -----> V'(-2+4,3+4)

V(-2,3) -----> V'(2,7)

Is correct

The true statement is: The transformation is a vertical translation. (Statement 3)

Let's analyze each statement:

1. The point moves two units up and four units to the right.

  - This statement is incorrect. The point moves four units up, not two units up.

2. The transformation rule is (x, y) → (x + 0, y + 4).

  - This statement is incorrect. The transformation rule should be (x, y) → (x, y + 4) because the point moves vertically by adding 4 to the y-coordinate.

3. The transformation is a vertical translation.

  - This statement is correct. The point moves vertically, changing only the y-coordinate.

4. The image is four units to the right of the pre-image.

  - This statement is incorrect. The image is at the same x-coordinate as the pre-image (-2), so it's not four units to the right.

5. The translation can be described as (x, y) → (x - 2, y + 7).

  - This statement is incorrect. The translation rule should be (x, y) → (x, y + 4) because the point only moves vertically.

Complete question:A translation moves point V(-2, 3) to V prime (-2, 7). Which of the following statements are true about the translation?
