Question

Find the inverse -4

a. -1/4
b. 1/4
c. 4
d. -4

Answer 1

c. 4

Explanation:

To find the inverse of a number, x, then you end up getting -x.

x = -4

- ( -4 ) = 4

Answer 2

For this case we must find the inverse of the following number:

-4

By definition we have that the inverse of a number multiplied by the number gives us 1 as a result.

Let "x" be the inverse of -4, then:

`x (-4) = 1\\-4x = 1\\x = - \frac {1} {4}`

So, the inverse of -4 is
`- \frac {1} {4}`

Answer:

`- \frac {1} {4}`
