Math Problem Statement
Solution
The inequality given is:
To solve this inequality, we need to break it down into two cases since it involves absolute value:
Case 1:
Solve for : Subtract 12 from both sides: Now, divide by 3:
Case 2:
This is equivalent to: Add 12 to both sides: Now, divide by -3 (remember to flip the inequality sign):
Combined solution:
The solution is:
This means that the inequality holds for in the intervals .
Graphing the solution:
- Draw a number line.
- There will be open circles at and since the inequality is strict (does not include equality).
- Shade the region to the left of (for ) and the region to the right of (for ).
Would you like further details on how to graph this, or do you have any questions?
Here are five related questions you might want to explore:
- What is the difference between a strict and non-strict inequality in absolute value problems?
- How do you solve absolute value inequalities with "less than" instead of "greater than"?
- How do you represent solutions to inequalities on a number line?
- Can you solve inequalities involving absolute values of quadratic expressions?
- How does the solution change when the inequality is instead of ?
Tip: When solving absolute value inequalities, always remember to consider both the positive and negative cases of the expression inside the absolute value symbol!
