Question

Which of the following is not an equivalent form of the compound inequality

x + 6 < 9 or x + 6 =>15



x < 3 or x =>9

A number line with an open circle on 3, a closed circle on 9, and shading in between.

x=> 9 or x < 3

A number line with an open circle on 3, shading to the left, and a closed circle on 9, shading to the right.

Answer 1

x < 3 or x ≥ 9
There would be an open circle at 3 and a closed circle at 9. Then, because it says OR, it's shading to the left of 3 and right of 9. It's the second one.

Answer 2

How do you find that out?
