Math Problem Statement
Solution
The problem is asking you to solve the inequality and identify the correct graph and solution.
Step 1: Solve the absolute value inequality
To solve , you can rewrite it as a compound inequality without the absolute value:
Step 2: Solve for
Now subtract 2 from all parts of the inequality:
This simplifies to:
So the solution to the inequality is between and , not including or .
Step 3: Identify the correct graph
From the given options, the correct graph is the one that shows the range , with open circles at and to indicate that these points are not included. This corresponds to Option D.
Final Answer:
The correct answer is D: Solution: and .
Do you want further details or have any questions? Here are 5 related questions to think about:
- What is the difference between strict and non-strict inequalities?
- How would the solution change if the inequality were ?
- How do you graph an inequality on a number line when dealing with absolute values?
- What happens if the inequality has a "greater than" sign instead of a "less than" sign?
- How would the solution change if we had ?
Tip: Always remember to check the boundaries carefully when solving absolute value inequalities!
