Select the correct answer.
Philip is snorkeling along a coral reef. He's wearing an altimeter, which tracks his elevation, Philip snaps a picture of the reef at an
elevation of -- 10 feet. Then he spots a nurse shark and swims to it for a closer look. By the time he reaches the shark, his
elevation changes by
---3 feet. What is Philip's elevation when he reaches the shark?
7 feet
-8 feet
13 feet

-14

Step-by-step explanation:

To calculate Philip's elevation when he reached the shark, add the two elevations given:  and  feet.

To represent the elevation of  feet, move  spaces in the negative direction from 0 on the number line. Next, to add  feet, move  spaces from  in the negative direction. You’ll reach -14.

Philip was at an elevation of -14 feet when he reached the nurse shark.

f(x) = y

f(-3) = -5
