Functions p and q are defined by these equations: p(x) = 5x + 30 q(x) = 11x − 24 What is (q − p)(6)? A. -42 B. 42 C. 18 D. -18

Respuesta :

Answer

D. -18

Step-by-step explanation:

p ( x ) = 5x + 30, q ( x ) = 11x -24

( q - p ) (6 ) = 11x -24 - ( 5x + 30 )

                  = 11.6 - 24 - 5.6 - 30

                  = 66 - 24 - 30 -30

                  = 42 -30 -30

                  = 12 -30

                  = -18
