Math Problem Statement
Which graph matches the compound inequality x ≤ 2 or x > 5?
Solution
The compound inequality is or . To interpret this, we need to understand:
- 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.
- 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 , not .
- Option 3: This is incorrect because the circle at 5 is closed, which implies instead of .
- Option 4: This is incorrect because it represents the solution for , 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 .
The correct answer is Option 1.
