Math Problem Statement
Solve the following absolute value inequality: |x - 5| ≥ 3
Solution
The given absolute value inequality is:
To solve this, we need to break it into two separate inequalities based on the property of absolute values:
Step 1: Solve
Step 2: Solve
Solution:
Thus, the solution to the inequality is:
Graphically:
- For , the solution is all values greater than or equal to 8.
- For , the solution is all values less than or equal to 2.
This corresponds to the second number line in the image, where:
- There is an open circle at and an arrow pointing to the left for values .
- There is an open circle at and an arrow pointing to the right for values .
Thus, the correct answer is the second number line.
Do you want any more details on solving this?
Here are some related questions to expand on this:
- How would the inequality change if the absolute value was less than instead of greater than?
- How do open and closed circles differ when graphing inequalities?
- What if the inequality was ? How would the solution change?
- What are some practical applications of absolute value inequalities?
- How can you graph inequalities involving quadratic functions?
Tip: When solving absolute value inequalities, remember to split them into two cases—one for the positive scenario and one for the negative scenario.
