Which of the following statements is necessarily true?
Given:
Which of the following statements is necessarily true?
We start with the inequality: \left|5x - 2\right| < 3x + 8
This absolute value inequality breaks into two separate inequalities:
5x - 2 < 3x + 8
5x - 2 > -(3x + 8)
Solving the first inequality: 5x - 2 < 3x + 8
Subtract from both sides: 2x - 2 < 8
Add to both sides: 2x < 10
Divide by : x < 5
Solving the second inequality: 5x - 2 > -(3x + 8)
Distribute the negative: 5x - 2 > -3x - 8
Add to both sides: 8x - 2 > -8
Add to both sides: 8x > -6
Divide by : x > -\frac{3}{4}
The solution is the intersection: x < 5 and x > -\frac{3}{4} . Hence, -\frac{3}{4} < x < 5 .
-\frac{3}{4} < x < 5
