For f(x) = 2x + 1 and g(x) = x^2 - 7, find (f+g)(x) a. x^2 + 2x - 6 b. 2x^2 - 15 c. x^2 + 2x + 8 d. 2x^3 - 6

Which is a graph of a proportional relationship?

Factor k2 - 17k + 16. a.(k - 2)(k - 8) b.(k - 1)(k + 16) c.(k - 1)(k - 16)

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.
