Math Problem Statement

5∣x+6∣−2≥28

Solution

Let's solve the inequality 5x+62285|x + 6| - 2 \geq 28.

Step 1: Isolate the absolute value expression

First, add 2 to both sides of the inequality: 5x+6305|x + 6| \geq 30

Now, divide both sides by 5: x+66|x + 6| \geq 6

Step 2: Break the absolute value inequality into two cases

The expression x+66|x + 6| \geq 6 means that the value inside the absolute value can either be greater than or equal to 6, or less than or equal to -6. So we have two cases to solve:

Case 1:

x+66x + 6 \geq 6 Subtract 6 from both sides: x0x \geq 0

Case 2:

x+66x + 6 \leq -6 Subtract 6 from both sides: x12x \leq -12

Step 3: Combine the solutions

The solution to the inequality is: x0orx12x \geq 0 \quad \text{or} \quad x \leq -12 In interval notation, the solution is: (,12][0,)(-\infty, -12] \cup [0, \infty)

This is the final solution.

Tip: When solving absolute value inequalities, always break the problem into two cases to account for both the positive and negative scenarios of the expression inside the absolute value.
