Math Problem Statement

b = {x : |x| ≥ 5}

Solution

The image shows the set notation:

b={xx5}b = \{x \mid |x| \geq 5\}

This represents the set of all real numbers xx such that the absolute value of xx is greater than or equal to 5.

Interpretation:

  • The absolute value x5|x| \geq 5 means that xx is either less than or equal to 5-5 or greater than or equal to 55.

In interval notation, this would be expressed as: x(,5][5,)x \in (-\infty, -5] \cup [5, \infty)

This describes two disjoint intervals on the number line:

  • x5x \leq -5
  • x5x \geq 5

Would you like any further details on this concept or have any questions?

Related Questions:

  1. How do we solve other inequalities involving absolute values?
  2. What is the geometric interpretation of x5|x| \geq 5 on the number line?
  3. Can you describe the difference between x>5|x| > 5 and x5|x| \geq 5?
  4. How can we express the solution of x5|x| \leq 5 in set notation?
  5. How do we handle compound inequalities involving absolute values, such as x24|x-2| \leq 4?

Tip: Always remember that absolute value inequalities split into two cases: one for the positive and one for the negative side of the number line.
