Math Problem Statement

|x - 2| ≥ 11

Solution

The given inequality is:

x211|x - 2| \geq 11

To solve this absolute value inequality, we can break it into two cases:

Case 1: x211x - 2 \geq 11

Solve for xx: x211x - 2 \geq 11 x11+2x \geq 11 + 2 x13x \geq 13

Case 2: (x2)11-(x - 2) \geq 11 or x211x - 2 \leq -11

Solve for xx: x211x - 2 \leq -11 x11+2x \leq -11 + 2 x9x \leq -9

Final Solution:

The solution set is: x9orx13x \leq -9 \quad \text{or} \quad x \geq 13

This means that xx can be any number less than or equal to 9-9 or greater than or equal to 1313.

Tip: For absolute value inequalities, remember that the inequality splits into two cases based on the definition of absolute value: one for the positive case and another for the negative case.
