Question

Which of the following inequalities best represents the graph above?

a > 9
a < 9
a ≤ 9
a ≥ 9

Answer 1

a ≤ 9

Explanation:

We know that its gonna be one of the ones with the line underneath because it has a closed circle (which means filled in). And we know that its going to be a ≤ 9 because my teacher taught me a trick. Whichever way the arrow or pointy side of the sign is facing that's the way the arrow is going to be facing.

Hope this helped!

Have a wonderful week!

Answer 2

The last answer would be correct because a closed cicle on a number line is less than/greater than or equal to and an open circle is less than or greater than. Because you are going to the left, into negatives, your answer would be d.
`a\geq 9`
