Question

Find the value of y, given value of x

Answer 1

a. -23.8

b. 36

c. 1.5

d. -14

Explanation:

Answer 2

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

substituting value of x, we get

y=2+4.3*-6=2-25.8=23.8

b. y = (x-3)² when x = 9

substituting value of x, we get

y=(9-3)²=6²=36

c. y=x-2 when x = 3.5

substituting value of x, we get

y=3.5-2=1.2

d. y=5x-4 when x = - 2

substituting value of x, we get

y=5*-2-4=-10-4=-14
