Math Problem Statement

|x-8|>=1

Solution

To solve the inequality x81|x - 8| \geq 1, follow these steps:

  1. Interpret the absolute value: The inequality x81|x - 8| \geq 1 means that the distance between xx and 8 is at least 1. This can be split into two cases: x81orx81x - 8 \geq 1 \quad \text{or} \quad x - 8 \leq -1

  2. Solve each case:

    • For the first case: x81x - 8 \geq 1 Add 8 to both sides: x9x \geq 9

    • For the second case: x81x - 8 \leq -1 Add 8 to both sides: x7x \leq 7

  3. Combine the solutions: The solution to the inequality is x9x \geq 9 or x7x \leq 7.

Thus, the solution is x7 or x9\boxed{x \leq 7 \text{ or } x \geq 9}.

Would you like further details or have any questions? Here are some related questions:

  1. How do you interpret absolute value inequalities?
  2. What is the difference between xab|x - a| \geq b and xab|x - a| \leq b?
  3. How do you graph the solution set for a disjoint inequality?
  4. Can you explain how absolute value inequalities relate to distance on a number line?
  5. How do you solve ax+bc|ax + b| \geq c for general values of aa, bb, and cc?

Tip: For absolute value inequalities like xab|x - a| \geq b, the solution is usually in two parts: either xx is at least bb units away from aa, which means xa+bx \geq a + b or xabx \leq a - b.
