Question

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.

Answer 1

can you send a screenshot or pic to me so i can solve easier? i can do it, i need a better base though.

Answer 5

the problem states the Celcius temperature range is -30 to 130

therefore:

-30 < temp in celcius < 130

but it wants an inequality that works for the fahrenheight range. they give you:

C = (5/9)(F − 32)

so you can plug this in for Celcius temperature to get

-30 < (5/9)(F − 32) < 130

solve for F
