=======================================================
Explanation:
Let's go through each answer choice and solve for x
----------------------------------------------------------------------
Choice A
|x+3| < -5
This has no solutions because |x+3| is never negative. It is either 0 or positive. Therefore, it can never be smaller than -5. So we can rule this out right away.
----------------------------------------------------------------------
Choice B
|x+8| < 2
-2 < x+8 < 2 .... see note below
-2-8 < x+8-8 < 2-8 ... subtract 8 from all sides
-10 < x < -6
We will have a graph where the open circles are at -10 and -6, with shading in between. This does not fit the original description. So we can rule this out too.
----------------------------------------------------------------------
Choice C
|x+3| < 5
-5 < x+3 < 5 .... see note below
-5-3 < x+3-3 < 5-3 .... subtracting 3 from all sides to isolate x
-8 < x < 2
We found our match. This graph has open circles at -8 and 2, with shading in between. The open circles indicate to the reader "do not include this value as a solution".
----------------------------------------------------------------------
note: For choices B and C I used the rule that [tex]|x| < k[/tex] turns into [tex]-k < x < k[/tex] where k is some positive number. For choice A, we have k = -5 which is negative so this formula would not apply.
