The label on the car's antifreeze container claims to protect the car between - 30C and 130C. To convert Celsius temperature to Fahrenheit temperature, the formula is C = 5/9 (F-32). Write and solve the inequality to determine the Fahrenheit temperature range at which this antifreeze protects the car

-22 ≤ temperature (F) ≤ 266

Step-by-step explanation:

Given that,

The label on the car's antifreeze container claims to protect the car between - 30C and 130C.

Formula to convert Celsius temperature to Fahrenheit

C = 5/9 (F - 32) 9C/5 = (F - 32) 9C/5 + 32 = FF = 9C/5 + 32 1)

-30C = ? F

F = 9 (-30) / 5 + 32

F = - 22

2)

130C = ? F

F = 9 (130) / 5 + 32

F = 266

The inequality to determine the Fahrenheit temperature range at which this antifreeze protects the car is

-22 ≤ temperature (F) ≤ 266
