Answer: Choice A</h3><h3>
-8 < x < 8</h3>
==============================================
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"
Answer:
5 + (-5) and 8 + (-8)
Step-by-step explanation:
Sum of zero means when you add them you get 0
so the others are wrong
-5 + (-5) = -10 because you have -5 and you add another -5
-12 + (-12) = -24 you start with -12 and you add another -12
Think of positive and negative numbers like floors in a building. Positive numbers are the stories and the negative numbers are the basement and sub-basement, zero is the ground level. So for 5 + (-5) you go up 5 floors, then you go down 5 floors. you end up on the ground level, 0.
