-(-9)
the distance from zero to nine

  and

Step-by-step explanation:

Given

Expression = -9

Required

Select all equivalent expressions

To do that, we examine each of the options.

First Option

This can be rewritten as

So, the expression becomes

Hence, |-9| is equivalent to -9

Second Option

So, the expression is not equivalent to -9

Third Option

This can be rewritten as

So, the expression becomes

Hence, -|-9| is equivalent to -9

Fourth Option

This can be rewritten as

Hence, -(-9) is not equivalent to -9

Fifth Option

The distance from 0 to 9

This is calculated as thus;

Hence, the difference from 0 to 9 is not equivalent to -9
