Math Problem Statement

Solve for w and graph the solution: 5 < |w - 3|

Solution

The inequality provided is:

5<w35 < |w - 3|

Step-by-Step Solution:

  1. Start by solving the absolute value inequality. We know that: w3>5|w - 3| > 5 This means that: w3<5orw3>5w - 3 < -5 \quad \text{or} \quad w - 3 > 5

  2. Solve each part of the inequality:

    • For w3<5w - 3 < -5: w<2w < -2
    • For w3>5w - 3 > 5: w>8w > 8

Solution:

The solution for ww is: w<2orw>8w < -2 \quad \text{or} \quad w > 8

Graphing the Solution:

  • The solution represents two intervals:
    • From -\infty to 2-2 (open at 2-2)
    • From 88 to \infty (open at 88)

On the number line, this would be shown as:

  • A ray extending to the left from 2-2 with an open circle at 2-2.
  • Another ray extending to the right from 88 with an open circle at 88.

Would you like further details or a specific visual for this graph?

Follow-up Questions:

  1. How would the graph look if the inequality was 5w35 \leq |w - 3|?
  2. What is the meaning of an "open circle" on a number line in inequality graphs?
  3. How would you write the solution in interval notation?
  4. What would happen to the solution if the inequality sign was reversed?
  5. How can absolute value inequalities be applied in real-life situations?

Tip:

When solving absolute value inequalities, always consider both the positive and negative cases of the expression inside the absolute value to cover all possible solutions.
