The label on a car's antifreeze container claims to protect the car between −30°C and 130°C. To covert Celsius temperature to Fahrenheit temperature, the formula is C equals five ninths times the quantity F minus thirty two.. Write a compound inequality to determine the Fahrenheit temperature range at which the antifreeze protects the car.

Negative thirty is greater than five ninths times the quantity F minus thirty two is greater than one hundred thirty.
Negative thirty is less than five ninths times the quantity F minus thirty two is less than one hundred thirty.
Negative thirty is less than five ninths times the quantity F minus thirty two.
Five ninths times the quantity F minus thirty two is less than one hundred thirty.

The compound inequality that represents the range in which the antifreeze is efficient is:

-22F ≤ T ≤ 266F

How to write the compound inequality?

First, we know that the antifreeze is efficient on the range between -30°C and 130°C.

Also remember that the formula to change units from Celsius to Fahrenheit is:

F = (C*9/5) + 32

Where C is the temperature in Celsius.

Then the lower limit is:

F = (-30*9/5) + 32 = -22F

The upper limit is:

F = (130*9/5) + 32 = 266F

Then the antifreeze is efficient in the range between -22F and  266F

, then the compound inequality that represents this is:

-22F ≤ T ≤ 266F
