A. rotate a XYZ 90° counterclockwise about the origin and then translate it 8 units to the right
B. reflect A XYZ across the line y = -x and then translate it 4 units to the left
C. rotate A XYZ 90° clockwise about the origin and then reflect it across X'Y' that resulted from
the rotation
D. reflect A XYZ across the line y = -x and then reflect it across X'Y' that resulted from the first
reflection
