    -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
