Math Problem Statement

Solve the following inequality algebraically: 4|4 - x| - 4 ≥ 32

Solution

The inequality presented is:

44x4324 |4 - x| - 4 \geq 32

Let’s solve this step-by-step:

Step 1: Simplify the Inequality

Start by adding 4 to both sides to eliminate the -4:

44x364 |4 - x| \geq 36

Step 2: Divide by 4

Divide both sides by 4:

4x9|4 - x| \geq 9

Step 3: Remove the Absolute Value

The inequality 4x9|4 - x| \geq 9 translates into two separate inequalities:

4x9or4x94 - x \geq 9 \quad \text{or} \quad 4 - x \leq -9

Step 4: Solve Each Inequality

  1. For 4x94 - x \geq 9:

    x5    x5-x \geq 5 \implies x \leq -5

  2. For 4x94 - x \leq -9:

    x13    x13-x \leq -13 \implies x \geq 13

Step 5: Combine the Solutions

The solution is:

x5orx13x \leq -5 \quad \text{or} \quad x \geq 13

So, the inequality holds for values of xx that are less than or equal to -5, or greater than or equal to 13.

Final Answer

(,5][13,)(-\infty, -5] \cup [13, \infty)

Tip: When solving absolute value inequalities, always remember that they represent two scenarios—one where the expression inside the absolute value is positive, and another where it's negative.
