What is the sum of x2-3x+7 and 3x2+5x-9

Iwill mark ad braniless pls just evens

Evaluate f(x) when x = 3. f(x) = 16x? +2 if 6 < x < 9 112 if 9 x < 13 a: 110 b: 56 c: 74 d: 12

1. 2y = 4 -x = -3 what is the solution to this system of equations? a) (2, 3) b) (-3, 2) c) (3, 2) d) (-3, 4) 2. 2x - y = 5 3x + 2y = 4 solve the system of equations. a) (3, 1) b) (0, 2) c) (2, -1) d) (9/7, 17/7)
