Answer:
a) x ≤ 5
b) x>5
Step-by-step explanation:
If the dot on the graph is filled in, it is ≥ or ≤. If the dot is not filled in, it is only < or >. Since the line is going down on a, x is less than or equal to 5 because the dot is filled in and the red line proceeds down into the negatives / less than 5. For b, the dot in not filled in so it is only greater than because the red line only proceeds up the line to bigger numbers than 5. So, x is greater than 5 which consists of 5.1,5.2,5.3, etc.
