Math Problem Statement

Solve the inequality: |x - 6| ≤ 10 for x.

Solution

We are given the inequality:

x610|x - 6| \leq 10

Step 1: Understand the Absolute Value Inequality

An absolute value inequality like x610|x - 6| \leq 10 means that the expression inside the absolute value, x6x - 6, is constrained to be between 10-10 and 1010. This is because the absolute value of a number represents its distance from 0, so the inequality x610|x - 6| \leq 10 can be rewritten as:

10x610-10 \leq x - 6 \leq 10

Step 2: Solve for xx

Now, to solve for xx, we add 6 to all parts of the inequality:

10+6x6+610+6-10 + 6 \leq x - 6 + 6 \leq 10 + 6

Simplifying the inequality:

4x16-4 \leq x \leq 16

Step 3: Conclusion

The solution to the inequality is:

4x16-4 \leq x \leq 16

Thus, the correct answer is Option B: 4x16-4 \leq x \leq 16.

  2. Solve x38|x - 3| \geq 8.
  3. What does x2<4|x - 2| < 4 represent on a number line?
  4. How would you solve x+1>3|x + 1| > 3?
  5. How does the solution change if we replace \leq with \geq in x610|x - 6| \leq 10?

Tip: For absolute value inequalities, remember that AB|A| \leq B becomes BAB-B \leq A \leq B, and AB|A| \geq B becomes two separate cases ABA \geq B or ABA \leq -B.
