Math Problem Statement

Solve the inequality: (- 3|6 - x| >= - 3)

Solution

To solve the inequality:

36x3-3|6 - x| \geq -3

we can follow these steps:

Step 1: Simplify the Inequality

Divide both sides by 3-3 (note that dividing by a negative reverses the inequality):

6x1|6 - x| \leq 1

Step 2: Solve the Absolute Value Inequality

The inequality 6x1|6 - x| \leq 1 means that the expression inside the absolute value is within 11 unit of 00, so we can write:

16x1-1 \leq 6 - x \leq 1

Step 3: Solve the Compound Inequality

Now, we solve the compound inequality 16x1-1 \leq 6 - x \leq 1 by isolating xx in the middle.

  1. Subtract 66 from all parts:

    16x16-1 - 6 \leq -x \leq 1 - 6

    Simplifying, we get:

    7x5-7 \leq -x \leq -5

  2. Divide by 1-1 (which reverses the inequality signs):

    7x57 \geq x \geq 5

    or equivalently:

    5x75 \leq x \leq 7

Solution

The solution to the inequality is:

x[5,7]x \in [5, 7]

This means that xx can take any value between 55 and 77, inclusive.

  3. How do you solve inequalities involving absolute values without reversing the inequality?
  4. What if the inequality was 36x>3-3|6 - x| > -3 instead? How would the solution change?

Tip: When dealing with absolute value inequalities, remember that dividing or multiplying by a negative number reverses the inequality symbol.
