Question

Part A -

Write an inequality that represents the possible depth, d, of the teacher's second dive.

Part B-
1. o-------->
2. (filled circle)------>
3. <--------o
4. <---------(filled circle)

Answer 1

Part A: x > -60

Part B: 3. <--------o

Explanation:

If the researchers explored a deeper depth than -60, that means the depth of the second dive must be more deeper than -60, not equal to it. so x > -60, and deeper depth means more larger negatives, and open circle stands for greater than/less than, so 3. would be the appropriate answer. hope this helps
