Answer 2

Answer:

1) D

2) C

3) D

4) B

Step-by-step explanation:

Background info: Left pointing vector is less than, right pointing is greater than. A circle without the middle filled in shows that value is excluded, a full circle shows included(which would be greater than or equal to, and less than or equal to)

With that you look at the sign for each problem and apply what I wrote above.

For example for question 1, x is greater than or equal to 8 so you pick the right/positive arrow, and the filled in circle.

Hope this helps!
