Question

Can you please explain how you got the answer? Also plz tell me what the closed and open circle mean again..

Answer 1

Answer: A

Step-by-step explanation:

• Open circle means that x does not equal that number. For example, the open circle on C is on 8, so that shows x is not equal to 8.

• Closed circle means that x does equal that number. For example on A, there is a closed circle on 8, so x could equal 8.

First, we need to solve the equation.

1. Subtract 200 frim 1200 -> 125x ≥ 1000.
2. Divide 125 from 1000 to isolate the x -> x ≥ 8

So, that means x is bigger than or equal to 8.

Answer 2

The answer should be A
