Question

someone...anyone...help pls.

Answer 1

one Im really confused with this one for sure

Answer 2

me too. i don't understand any of these ugh.

Answer 3

Let C denote the center of dilation, and r the scaling factor. If point Q is the image of point P under the dilation, then vector CQ = r (vector CP).

Here C = O = (0,0) is the origin and r = 2.5 P = P = (1, -2).
So vector CP = <1,-2>
So vector CQ = r ( vector CP ) = 2.5 <1, -2>
So Q = C + vector CQ = (0,0) + <2.5, -5>
so I believe it is the first one
A

Answer 4

that was hard
