Answer: Choice A
-8 < x < 8
==============================================
Explanation:
We're told that x is greater than -8, so x > -8 which is the same as -8 < x
At the same time, x is also less than 8, meaning x < 8
Combining -8 < x and x < 8 together forms the compound inequality
-8 < x < 8
Basically saying "x is some number between -8 and 8. X cannot equal -8 nor can it equal 8"
On a number line, we can visually show this by having two open circles at -8 and 8, then shading the region between the open circles. The open circles tell us "this value is not part of the solution set"
