Math Problem Statement

Solve and graph the compound inequality: -8 < x - 6 < 10.

Solution

The problem involves solving and graphing the compound inequality 8<x6<10-8 < x - 6 < 10. Let's break it down step by step.

Step 1: Solve the compound inequality

The compound inequality can be split into two separate inequalities:

  1. 8<x6-8 < x - 6
  2. x6<10x - 6 < 10

Inequality 1: 8<x6-8 < x - 6

  • Add 6 to both sides to isolate xx: 8+6<x-8 + 6 < x 2<x-2 < x This simplifies to: x>2x > -2

Inequality 2: x6<10x - 6 < 10

  • Add 6 to both sides to isolate xx: x6+6<10+6x - 6 + 6 < 10 + 6 x<16x < 16

Step 2: Combine the inequalities

Now that we have x>2x > -2 and x<16x < 16, we combine them to get: 2<x<16-2 < x < 16

Step 3: Write the solution in interval notation

The solution set in interval notation is: (2,16)(-2, 16)

Step 4: Graph the solution

On a number line, the solution would be represented as an open interval from 2-2 to 1616, meaning xx can take any value between 2-2 and 1616 but not including 2-2 and 1616.

Answer

So the correct solution set is (2,16)(-2, 16).

Here are 5 related questions that might help expand your understanding:

  1. What would be the solution set if the inequality was 8x610-8 \leq x - 6 \leq 10?
  2. How would the solution change if the inequality was 8<x610-8 < x - 6 \leq 10?
  3. Can you graph the solution set on a number line?
  4. What does it mean when the solution set is empty (i.e., \emptyset)?
  5. How would the interval notation change if the inequalities were "greater than or equal to" instead of "greater than"?

Tip: When working with compound inequalities, solve each part separately and then combine the results to find the solution set.
