Question

Which inequality has a closed circle when it is graphed on a number line?

A.
$x > 0.4$


B.
$x > - 3$


C.
$x < 4$


D.
$x \geqslant 3$
​

Answer 1

Answer:

D

Step-by-step explanation:

The line underneath the greater than sign indicates that x is greater than or equal to 3, meaning x could be 3, 4, 5, etc. Therefore, if you were to graph this, you would have a closed circle on 3 because a closed circle indicates that x could be the number 3 or anything greater than 3.
