Complete question :

During a science experiment, Daniel noted the starting temperature of a -4°F. At the end of the experiment, the change in temperature was -5°F. What was the final temperature?

A.-1 B.1 C.9 D.-9

D.) - 9

Step-by-step explanation:

Given the following :

Temperature at the start of experiment = - 4°F

At the end of experiment, change in temperature = - 5°F

This means between the temperature at the start of the experiment was - 4°F and during the cause of the experiment, there was a change in temperature of - 5°F.

Hence, the final temperature is the sum of the initial temperature and and the temperature change recorded.

Initial temperature + temperature change

-4°F + (-5°F)

- 4°F - 5°F = - 9°F

Hence, final temperature = - 9°F

the answer to this is:

12/7
