Math Problem Statement

|w| > 4. Graph the solution to the inequality on the number line.

Solution

The inequality in the image is w>4|w| > 4. To solve and graph this on the number line, let's break it down:

Step 1: Interpret the inequality

The absolute value inequality w>4|w| > 4 means that the value of ww is more than 4 units away from 0. Therefore, ww could be either:

  • Greater than 4 (i.e., w>4w > 4), or
  • Less than -4 (i.e., w<4w < -4).

Step 2: Solution

So the solution to w>4|w| > 4 is: w<4orw>4w < -4 \quad \text{or} \quad w > 4

Step 3: Graph on the number line

  1. Plot open circles at 4-4 and 44 because the inequality is strict (>>, not \geq).
  2. Shade to the left of 4-4 and to the right of 44, indicating that ww is either less than 4-4 or greater than 44.

This is how you would graph the solution on the number line.

Let me know if you'd like any additional details or explanations.

Here are five related questions to practice:

  1. How would the graph change if the inequality was w4|w| \geq 4?
  2. What would be the solution to w<3|w| < 3?
  3. How do you solve and graph x2>5|x - 2| > 5?
  4. What are the key differences between solving w>4|w| > 4 and w4|w| \leq 4?
  5. How do you solve absolute value inequalities that include variables on both sides, like 2x1>5|2x - 1| > 5?

Tip: Always remember to use open or closed circles depending on whether the inequality is strict or includes equality!
