The temp. inside your mother's deep freezer is set for -2 degrees f. the manufacturer guarantees the actual temperature will fall within 4 degrees f of the temp. to which the freezer is set. write an inequality that can be used to describe this situation.
|t+2| < 4
|t-2| < 4

|t+2| < 4

Step-by-step explanation:

If the temperature is set to -2 F and temperature will fall within 4 degrees F mean that actual temperature will be between 2 (-2 + 4) and  -6 (-2 -4).

First inequality can be expanded as follows :

|t+2| < 4

-4 < t+2 < 4

-4 - 2 < t < 4 - 2  

-6 < t < 2

i think that you should ask google for the answer to that problem because if we don't know it google does

the answer is two. hope this !
