Math Problem Statement
-5 < x + 2 and x + 4 ≤ 9
Solution
The image shows the compound inequality:
Let's solve each part of the inequality separately:
-
First Inequality: Subtract 2 from both sides: Simplifying:
-
Second Inequality: Subtract 4 from both sides: Simplifying:
Combine the results:
The solution is:
Final Answer:
The solution in interval notation is:
