A vertical stretching<span> is the </span>stretching<span> of the graph away from the x-axis.
It means you simply need to multiply the scale factor with the x-values.
</span>If point H is located at <span>(-2, 0),and the scale factor is 2,then the stretch would be (-2*2.5,0)
Hence,the new point will be:
A.(-5,0).
</span>
Since the origin is the center of the dilation, this means we simply multiply every coordinate of the given point by the scale factor.
(6,12) would turn into (18,36) since
6*3 = 18
12*3 = 36
The final answer is (18,36)
The area of the place mat, 126 in^2, is equal to L * W, where L = 4(W/2 - 9).
We must solve this equation for the width, W.
Then 126 in^2 = W * 4(w/2 - 9). Simplifying, 126 in^2 = W(2W - 36), and
63 in^2 = W(W - 18). Then W^2 - 18W - 63 = 0. This is a quadratic equation with coefficients a = 1, b = -18 and c = -63; the discriminant is 576.
Thus, the solutions are:
-(-18) plus or minus √576
W = -----------------------------------------
2
18 plus or minus 24
= --------------------------------- = {21, -3}. Omit the negative result, since
2 W = width must be a positive quantity.
Thus, W = 21 inches.
The answer is B. because "x" can have only one "y" value, so B. has to be the answer considering that in the other options "x" has multiple "y" values
