Math Problem Statement

Solve the following absolute value inequality: (|x + 8| / 7) ≥ 1.

Solution

The problem in the image is asking to solve the absolute value inequality:

x+871\frac{|x + 8|}{7} \geq 1

Step 1: Remove the fraction

To eliminate the fraction, multiply both sides of the inequality by 7:

x+87|x + 8| \geq 7

Step 2: Solve the absolute value inequality

The general rule for solving inequalities of the form AB|A| \geq B is that:

ABorABA \geq B \quad \text{or} \quad A \leq -B

In this case, A=x+8A = x + 8 and B=7B = 7. So, we split the inequality into two cases:

  1. x+87x + 8 \geq 7
  2. x+87x + 8 \leq -7

Step 3: Solve each inequality

  1. x+87x + 8 \geq 7 x78x \geq 7 - 8 x1x \geq -1

  2. x+87x + 8 \leq -7 x78x \leq -7 - 8 x15x \leq -15

Final Answer:

The solution to the inequality is: x1orx15x \geq -1 \quad \text{or} \quad x \leq -15

Thus, the answer is:

  • x1x \geq -1 and x15x \leq -15.
