If the rectangle WXYZ was reflected about the x-axis, the resulting image would have coordiantes W’(-8,5) X’(-7,-5) Y’(8,10) and

(4,-10). What were the coordinates of the preimage WXYZ?

W(8,5) X(7,-5) Y(-8,10) Z(-4,-10) since it was a reflection over the X-axis then the X values will change but the Y values won’t. If the x value is positive in the pre-image then when it’s reflected over the X-axis then the x value will be negative in the image. They Y values stay the same as in the pre-image because the shape isn’t being reflected over the Y-axis meaning it’s not being moved up or down so the Y values remain the same unless the pre-image is reflected over the Y-axis

Answer:

W'(8,5) X'(7,-5) Y'(-8,10) Z'(-4,-10)

I would say that this is the answer, but when I graphed it out, it didn't make a rectangle, so I believe that you or your teacher typed something wrong.

<span>2.Which type of variables are usually on the y-axis and represent output?
</span>they usually are the dependent variables, that is, they depend on the x value, such as velocity, price, income.

3.Which type of variables are usually on the x-axis and represent input?
those are the independent variables such as time, distance, price.

the slope of an horizontal line is zero.

<span>5.Find the slope of 2x + 4y = 12
</span>the general form of the line is:
4y = - 2x + 12
y = -(1/2)x + 3

hence the slope is -1/2

If f(x) = 1/2x-14,then f^-1(x)=
Alik [6]

Answer:

f ^-1 (x) = 2x+28

Step-by-step explanation:

f(x) = 1/2x-14

Replace f(x) with y

y = 1/2 x -14

Exchange x and y

x = 1/2 y -14

Solve for y

Add 14 to each side

x+14 = 1/2 y -14+14

x+14 = 1/2 y

Multiply each side by 2

2(x+14)= 1/2 y*2

2x+28 = y

The inverse function is

f ^-1 (x) = 2x+28
