Question

Find the zero of the linear function y=160-4x

Answer 1

x = 40

Explanation:

given

y = 160 - 4x

To find the zero let y = 0 in the equation and solve for x

0 = 160 - 4x ( add 4x to both sides )

4x = 160 ( divide both sides by 4 )

`(4)/(4)` x =
`(160)/(4)` , that is

x = 40

the zero of the linear function is x = 40
