Answer:
28. x > 1 (greater than)
29. x </= -1 (less than or equal to)
30. x >/= 3 (greater than or equal to)
31. x < 0 (less than)
Step-by-step explanation:
If the circle on the graph is open, it's "less than" or "greater than", but not "equal to". The open circle means that number is excluded from the answer set.
If the circle on the graph is closed, it's "less than or equal to" or "greater than or equal to"
Then the "less than" or "greater than" part depends on which way your arrow is pointing.
