Question

In my FLVS math test I found 4 number lines. 2 with a closed circle on the seven, and 2 with an open circle on the seven. Why the difference?

Answer 1

If the circle is open, it means that the inequality's sign will be > or <.

If the circle is closed, it means that the inequality's sign will be ≥ or ≤.

Thanks for the points. Have a nice day.
