ABC was dilated around (–1,–3) by a scale factor of 4, then reflected over y=–x, and finally rotated 180 degrees counterclockwise , find ABC given A"(1, –5), B"(–7, 7), and C"(–7, –9)

Three numbers x, y, and z are in the ratio 2: 7: 8. if 12 is subtracted from y, then three numbers form a geometric sequence (in the order x, y–12, z). find x, y, and z. there are 2 sets.
