D) Vertices: (1, -1), (-11, -1); Foci: (-15, -1), (5, -1)
Answer:
Option C.
Step-by-step explanation:
It is given that the dilation rule is
. It means the center of dilatation is point Q and scale factor is 2.5.
Scale factor is the ratio of distance from center to the image of a point and distance from center to the corresponding point.

It is given that QU=4 and scale factor = 2.5.

Multiply both sides by 4.


We know that



The distance between U' and U is 6 units.
Therefore, the correct option is C.

To solve, we will need to evaluate:

We're not done yet because we need to simplify 13673/20:

Hope this helps!☺
Let the un know number be p
p + 1½ = 3/8
p + 3/2 = 3/8
p= 3/8 – 3/2
p= –9/8✅
