Given ƒ(x) = − 1 2 x + 7, find x when ƒ(x) = 10. a) −6 b) −3 c) 2 d) 7

x = -1/4

Step-by-step explanation:

Since f(x) is given as 10 , just substitute into the equation given , that is

10 = -12x + 7

Collecting the like terms , we have

12x = 7 - 10

12x = -3

x = -3/12

x = -1/4

step-by-step explanation:

if x = 2 you have to find x to finish the problem

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.
