Square abcd was translated using the rule (x, y) → (x – 4, y + 15) to form a'b'c'd'. what are the coordinates of point d in the pre-image if the coordinates of point d’ in the image are (9, –8)?

(13,-23)

Step-by-step explanation:

A sqaure ABCD was translated using the rule (x,y→(x-4,y+15) to form A'B'C'D'. Now the coordinates of point D in the iamge are (9,-8) therefore pre image of point D is

(by using property when a number go form left to right side then sign changes of a number)

( by using property of addition)

similarly, we find value of y

hence, the coordinate of D in pre iamge is (13,-23).

hi how are you doing today? if you ever need just tell me

step-by-step explanation:

sas (side angle side)

aa(angle angle)

sss(side side side)

sas you have to find two sides with an angle in between

aa you find two angles because it will always add up to 180

sss find all sides
