Question

Find the value of y, given value of x.

a. y= 2 + 4.3x when x = -6

b. y= (x – 3)2 when x = 9

c. y=x – 2 when x = 3.5

d. y = 5x – 4 when x = -2

Answer 1

Explanation:

a. y = 2 + 4.3(-6)

y= 2- 25.8

y= -23.8 or y= -24

b. y= (9-3)2

18-6=12

c. y= 3.5-2

y= 1.5

d. y= 5(-2) - 4

y= -10-4

y= -14
