Answer:
D
Step-by-step explanation:
It seems to be A but it's not A because the ratio of their corresponding sides is 1:2

When dilation is about the origin, as it is here in every case, the image point coordinates are the original (pre-image) coordinates multiplied by the scale factor.
1. Multiply every coordinate value by 5:
... W' = (-5, 10), X' = (-15, -5), Y' = (25, -5), Z' = (15, 10)
2. Multiply every coordinate value by 1/3:
... A' = (-2, 5), B' = (0, 5/3), C' = (1, 10/3)
3. A' = (2, 8), B' = (6, 2), C' = (2, 2)
4. The image coordinates are 5 times the original coordinates, so ...
... the scale factor of the dilation is 5.
The Answer is the last one. it equals -1
Answer:
v = -2
Step-by-step explanation:
-9v – 9 = -27
add 9 to each side
-9v – 9+9 = -27+9
-9v = -18
divide by -9
-9v/-9 = -18/-9
v = 2
Answer:
plug the a back in
3(6)=18 if the answer is 18 then your right
18=18
