Which of the following coordinates are exactly 5 units from (2, -1)? select all that apply. (3, 4) (5, 3) (-2, 2) (-3, -1)

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.
