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.
Subtract 200 frim 1200 -> 125x ≥ 1000. Divide 125 from 1000 to isolate the x -> x ≥ 8 So, that means x is bigger than or equal to 8.
