Math Problem Statement

If |x - 5| < 1, what is the answer in intervals

Solution

The inequality x5<1|x - 5| < 1 represents the absolute value of x5x - 5 being less than 1. This means the distance between xx and 5 must be less than 1.

We can break this into two inequalities:

1<x5<1-1 < x - 5 < 1

Now, solve for xx:

  1. Add 5 to all parts of the inequality: 1+5<x5+5<1+5-1 + 5 < x - 5 + 5 < 1 + 5 4<x<64 < x < 6

So, the solution in interval notation is:

(4,6)(4, 6)

This means that xx lies strictly between 4 and 6.


Would you like a more detailed explanation of absolute value inequalities or have any questions about this? Here are some related questions you could explore:

  1. How would you solve an absolute value equation like x5=1|x - 5| = 1?
  2. What does x+3>2|x + 3| > 2 represent in interval form?
  3. How do you graph the inequality x5<1|x - 5| < 1?
  4. Can absolute value inequalities have solutions for all xx?
  5. What happens if the inequality is x51|x - 5| \geq 1?

Tip: To solve absolute value inequalities like this, always rewrite the inequality without the absolute value by considering both the positive and negative cases.
