Question

Find the value of y for the given value of x.a. y = 10x; x = -3b. y = 6 - 2x; x = 11 c. y = 4x + 5; x = 1/2

Answer 1

Part a

y = 10x

For x=-3

substitute the value of x in the equation and evaluate it

y=10(-3)=-30

Part b

y = 6 - 2x

For x=11

y=6-2(11)=-16

Part c

y = 4x + 5

For x=1/2

y=4(1/2)+5=7
