We are asked to identify which graph shows the solution for the given inequality.
|2x+5|≤ 3
To do this, we will create a compound inequality by removing the absolute value. In this case, the solution set is any number less than or equal to 3 away from the midpoint in the positive direction and any number less than or equal to 3 away from the midpoint in the negative direction.
Absolute Value Inequality:& |2x+5|≤ 3
Compound Inequality:& -3 ≤ 2x+5 ≤3
We can split this compound inequality into two cases, one where 2x+5 is greater than or equal to -3 and one where 2x+5 is less than or equal to 3.
2x+5≥- 3 and 2x+5≤ 3
Let's isolate x in both of these cases before graphing the solution set.
This inequality tells us that all values less than or equal to - 1 will satisfy the inequality.
Solution Set
The solution to this type of compound inequality is the overlap of the solution sets. Let's combine our cases back into one compound inequality.
First Solution Set:& - 4≤ x
Second Solution Set:& x≤- 1
Intersecting Solution Set:& - 4≤ x≤- 1
Graph
The graph of this inequality includes all values from - 4 to - 1, inclusive. We show this by using closed circles on the endpoints.
