If rectangle abcd, defined by the coordinates a(0, 0), b(0, -4), c(-2, -4), d(-2, 0), is dilated by a scale factor of 2, with resulting vertex a' at (2, 4), what is the center of the dilation? a) (0, 0) eliminate b) (2, 4) c) (0, -4) d) (-2, -4)

D) (-2, -4).

Step-by-step explanation:

Let be the center of dilation. Imagine that is the center of origin of a new Cartesian Plane. What would the coordinates of point A and A' on the new plane?

Dilating about the "origin" of the new plane by a factor of two will give the point , also on the new plane.

For coordinates of A' on the original plane,

.

As a result,

.

.

.

In other words, is the center of dilation.

step-by-step explanation:

well, you see here, jamal was born to 2 parents, his mother who he lives with and his father who left at a young age and who happens to be younger than him. he stole cookies because he has to steal food due to the fact that he spends his government poverty checks on pot and women.
