Solve |3x - 2| ≥ 4: Absolute Value Inequality Challenge

Question

Given:

3x24 |3x - 2| \geq 4

Which of the following statements is necessarily true?

Step-by-Step Solution

To solve the inequality 3x24 |3x - 2| \geq 4 , we separate it into:

3x24 3x - 2 \geq 4 or 3x24 3x - 2 \leq -4 .

For 3x24 3x - 2 \geq 4 , add 2 to both sides:

3x6 3x \geq 6

Divide by 3:

x2 x \geq 2

For 3x24 3x - 2 \leq -4 , add 2 to both sides:

3x2 3x \leq -2

Divide by 3:

x23 x \leq -\frac{2}{3}

Therefore, the solution is x2 x \geq 2 or x23 x \leq -\frac{2}{3} .

Answer

x2 x \geq 2 or x23 x \leq -\frac{2}{3}
