[02.06] the label on the car's antifreeze container claims to protect the car between −30°c and 130°c. to convert celsius temperature to fahrenheit temperature, the formula is c = 5 over 9 (f − 32). write and solve the inequality to determine the fahrenheit temperature range at which this antifreeze protects the car.

It is given that the label on the car's antifreeze containers claims to protect the car between and  .

Convert Celsius temperature to Fahrenheit temperature;

Using the formula:

Multiply both sides by we get;

Simplify:

Add 32 to both sides of an equation:

Simplify:

                     ......[1]

Substitute the value   in [1];

or

Similarly, Substitute the value in [1] we have;

or

then, we have

Therefore, the inequality    that determine the Fahrenheit temperature range at which this antifreeze protects the car is;
