Question

Find the x-intercept of y = 4x - 64. A) (3, 0) B) (64, 0) C) (-63, 0) D) (0.602, 0)

Answer 1

A

Explanation:

Answer 2

For this case we have the following equation:

`y = 4x-64`

To find the intersection with the x-axis we make
`y = 0`.

So, substituting y = 0 we have:

`0 = 4x-64\\-4x = -64\\4x = 64\\x = \frac {64} {4}\\x = 16`

The intersection with the x axis is:

`(x, y) :( 16,0)`

Answer:

`(x, y) :( 16,0)`
