The ordered pair below is a solution to which equation? (3, 15)
O A. y.
O B. y = 5x
O C. y*
O b. y = 3x

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.

Can someone me with #s 8, 9, and 11. with just one of the three also works. prove using only trig identities.

Which of the following constants can be added to x2 - 3x to form a perfect square trinomial?
