Math Problem Statement

Solve the inequality shown in the image.

Solution

The inequality in the image is:

x7|x| \leq 7

Solution:

To solve this absolute value inequality, we need to understand that the absolute value expression x7|x| \leq 7 means that the value of xx is within 7 units from 0 on the number line.

This can be translated into a compound inequality:

7x7-7 \leq x \leq 7

Conclusion:

The solution to the inequality x7|x| \leq 7 is:

x[7,7]x \in [-7, 7]

Explanation:

This means that xx can take any value from 7-7 to 77, inclusive.

  2. What is the geometric interpretation of the absolute value inequality?
  3. How would the solution change if the inequality was x>7|x| > 7?
  4. Can you explain how to solve a more complex absolute value inequality, like 2x35|2x - 3| \leq 5?
  5. What happens when the absolute value is set equal to a negative number?

Tip: When solving absolute value inequalities, always consider both the positive and negative scenarios!
