Math Problem Statement

|2x−10|≥16

Solution

To solve the inequality 2x1016|2x - 10| \geq 16, we need to consider the definition of absolute value. Recall that for any expression AB|A| \geq B, where BB is a positive number, the solution breaks into two cases:

  1. ABA \geq B
  2. ABA \leq -B

In this case, A=2x10A = 2x - 10 and B=16B = 16. Thus, we have two inequalities:

  1. 2x10162x - 10 \geq 16
  2. 2x10162x - 10 \leq -16

Solving the first inequality:

2x10162x - 10 \geq 16

Add 10 to both sides:

2x262x \geq 26

Now, divide by 2:

x13x \geq 13

Solving the second inequality:

2x10162x - 10 \leq -16

Add 10 to both sides:

2x62x \leq -6

Now, divide by 2:

x3x \leq -3

Final Solution:

The solution to the inequality is:

x13orx3x \geq 13 \quad \text{or} \quad x \leq -3

In interval notation, the solution is:

(,3][13,)(-\infty, -3] \cup [13, \infty)
