The label on antifreeze container claims to protect the car between -40 celsius and 140 celsius to convert celsius temperature to fahrenheit temperature the formula is c=5/9(f-32). write a compound inequality to determine the fahrenheit temperature range at which the antifreeze protects the car.

a. -40 < 5/9(f-32)
b. 5/9(f-32) < 140
c. -40 > 5/9(f-32) > 140
d. -40 < 5/9(f-32) < 140
