Math Problem Statement

Graph the solution to the inequality |w| < 8 on the number line.

Solution

From the image, it appears the problem asks to graph the solution for the inequality w<8|w| < 8. Let's analyze and solve it correctly.

Steps to Solve:

  1. Understand Absolute Value Inequality:

    • The inequality w<8|w| < 8 means the values of ww are within 8 units from 0. In mathematical terms, this translates to: 8<w<8-8 < w < 8
    • This indicates an open interval where ww lies between 8-8 and 88 (excluding 8-8 and 88).
  2. Graph Representation:

    • On the number line, the solution should be represented as a line segment between 8-8 and 88 with open circles at 8-8 and 88, since the values at these points are not included in the solution.

Issue in the Uploaded Graph:

The graph shown in your response incorrectly represents the inequality w<8|w| < 8. Instead, it seems to be incorrectly marking the range from 88 to a larger value, or the setup is not consistent with the correct representation of the inequality.

Correct Graph:

  • On the number line, draw a line segment starting just after 8-8 and ending just before 88.
  • Use open circles (not filled) at 8-8 and 88.

Would you like me to generate a clean and clear image of the correct graph? Let me know if you have any questions or would like further clarification.


Follow-up Questions:

  1. Why is it necessary to use open circles for 8-8 and 88?
  2. How would the graph change if the inequality were w8|w| \leq 8?
  3. How do absolute value inequalities translate into compound inequalities?
  4. Can you explain why the solution excludes w=8w = -8 and w=8w = 8?
  5. What does the inequality w>8|w| > 8 look like on a graph?

Tip:

When solving absolute value inequalities, always rewrite them into equivalent compound inequalities for clarity before graphing.
