Math Problem Statement
Solution
The problem involves solving and graphing the compound inequality . Let's break it down step by step.
Step 1: Solve the compound inequality
The compound inequality can be split into two separate inequalities:
Inequality 1:
- Add 6 to both sides to isolate : This simplifies to:
Inequality 2:
- Add 6 to both sides to isolate :
Step 2: Combine the inequalities
Now that we have and , we combine them to get:
Step 3: Write the solution in interval notation
The solution set in interval notation is:
Step 4: Graph the solution
On a number line, the solution would be represented as an open interval from to , meaning can take any value between and but not including and .
Answer
So the correct solution set is .

- How would the solution change if the inequality was ?
- Can you graph the solution set on a number line?
- What does it mean when the solution set is empty (i.e., )?
- How would the interval notation change if the inequalities were "greater than or equal to" instead of "greater than"?
Tip: When working with compound inequalities, solve each part separately and then combine the results to find the solution set.
