Math Problem Statement
Solution
We are tasked with solving the inequality:
Step 1: Understanding the Absolute Value Inequality
An inequality involving absolute value can be split into two separate inequalities. For , this means:
Step 2: Solve Each Inequality
-
- Add 2 to both sides:
-
- Add 2 to both sides:
Step 3: Combine the Solutions
The solution is or . This describes two separate intervals: one where is greater than or equal to 11, and one where is less than or equal to -7.
Conclusion:
The correct answer is: This corresponds to the second option in the list.
Do you need more details or explanations? Here are five related questions to consider:
- What is the general approach for solving absolute value inequalities?
- Can we apply this method to absolute value inequalities involving quadratic expressions?
- How do you graph the solution of an absolute value inequality on a number line?
- What are the differences between strict inequalities and non-strict inequalities in absolute value problems?
- How does solving absolute value equations differ from solving inequalities?
Tip: When solving absolute value inequalities, always remember to split the inequality into two cases: one where the expression inside is positive, and one where it's negative!
