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)

D = (13 - 23)

Step-by-step explanation:

x, y -> x-4 y+15

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.
