Question 1

A has the coordinates (–4, 3) and B has the coordinates (4, 4). If DO,1/2(x, y) is a dilation of △ABC, what is true about the image △A'B'C'? Check all that apply.AB is parallel to A'B'.DO,1/2(x, y) = The distance from A' to the origin is half the distance from A to the origin.The vertices of the image are farther from the origin than those of the pre-image.A'B' is greater than AB.

Revolt · Accepted Answer

AB is parallel to A'B'.; DO,1/2(x, y) =; The distance from A' to the origin is half the distance from A to the origin.

Question 8

△RST is dilated with the rule DT,1/3 (x, y), where the center of dilation is T(3, –2).

Revolt · Accepted Answer

The distance between the x-coordinates of R and T is .: 3; The distance between the y-coordinates of R and T is .: 6; R' is from T, so the coordinates of R' are .: 1 unit left, 2 units up; R' is from T, so the coordinates of R' are .: (2, 0)
