Math Problem Statement

Which graph matches the compound inequality x ≤ 2 or x > 5?

Solution

The compound inequality is x2x \leq 2 or x>5x > 5. To interpret this, we need to understand:

  1. x2x \leq 2 means that the solution includes all values less than or equal to 2, which would be shown with a closed circle at 2 and a line extending to the left.
  2. x>5x > 5 means all values greater than 5, which would be shown with an open circle at 5 and a line extending to the right.

Now let's analyze the options:

  • Option 1: This shows a line extending left from 2 (with a closed circle at 2) and a line extending right from 5 (with an open circle at 5), which matches the given inequality.
  • Option 2: This is incorrect because both circles are filled, suggesting x5x \geq 5, not x>5x > 5.
  • Option 3: This is incorrect because the circle at 5 is closed, which implies x5x \geq 5 instead of x>5x > 5.
  • Option 4: This is incorrect because it represents the solution for 2x52 \leq x \leq 5, which is a different range.
  • Option 5: This is incorrect because there is no line extending from 5, and it misrepresents the inequality.
  • Option 6: This is incorrect because both ends have closed circles, which would mean x5x \geq 5.

The correct answer is Option 1.

  1. How do you graph compound inequalities that use "and" instead of "or"?
  2. What is the difference between open and closed circles on a number line?
  3. How do you write inequalities that include absolute values?
  4. What types of problems require compound inequalities?
  5. Can you convert compound inequalities into interval notation?

Tip: Remember that closed circles on a graph represent values included in the solution, while open circles indicate values that are excluded.
