Find the average rate of change for f(x) = x2 − 3x − 10 from x = −5 to x = 10.

What is the distance between the points 4,10 and -3,-14 on the coordinate plane

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.
