An animal trainer at the aquarium trains bottlenose dolphins to jump
for performances. One dolphin
jumped out of the water at a height
of 15 feet and then dove back under
the water to a depth of 20 feet. Write
an expression to represent the vertical
distance the dolphin traveled. What is
the vertical distance?

35 feet up and down

Step-by-step explanation:

15 up plus 20 down= 35 feet.

Step-by-step explanation:

15+20=35

the correct answer is b.

this is because an open circle means < or > & since the line goes left it is < -3.

the next one has a filled circle so it can only be ≥ or ≤ and since the line goes right from 1 it is ≥ 1
