In the figure, polygon abcd is dilated by a factor of 2 to produce a′b′c′d′ with the origin as the center of dilation. point a′ is at , and point d′ is at . nextreset

You did not attach any picture to solve this problem. We cannot calculate for the value of A’ and D’ without the correct graph. However, I think I found the correct graph (see attached), please attach it next time.

So we are given that the figure is dilated by a factor of, meaning that all of its end points are multiplied by 2. By this rule, all we have to do is to simply multiply the initial coordinates of A and D by 2 to get A’ and D’, that is:

A’ = (-1 * 2, -1 * 2) = (-2, -2)

D’ = (2 * 2, -1 * 2) = (4, -2)

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3
