Question

Easy question! Please help! And please tell me which line to use! (open circle or closed circle)

Answer 1

See below

Explanation:

The inequality is d<-80 since the problem states you go deeper than -80 feet.

As for graphing the inequality, you use a open circle with the arrow pointing left.

<= means closed

>= means closed

< means open

> means open

Answer 2

Question: You need to figure out the inequality. Here is the full question: On their first dive, scientists explore a part of the ocean floor that is 80 feet below sea level. This depth can be represented by the integer -80. On their second dive, they explore a deeper depth. Write an inequality that represents the possible depth, d, of the scientist's second dive. After you figure that out you can answer the question above.

d < -80

Open ended at -80 pointing toward -200
