Question

The label on the car's antifreeze container claims to protect the car between −40°C and 140°C. To covert Celsius temperature to Fahrenheit temperature, the formula is C equals five ninths times the quantity F minus thirty two.. Write a compound inequality to determine the Fahrenheit temperature range at which the antifreeze protects the car.

Negative forty is less than five ninths times the quantity F minus thirty two.

Five ninths times the quantity F minus thirty two is less than one hundred forty.

Negative forty is greater than five ninths times the quantity F minus thirty two is greater than one hundred forty.

Negative forty is less than five ninths times the quantity F minus thirty two is less than one hundred forty.

Answer 1

Answer: FLVS ALGEBRA 1

The answer would be D

Explanation:

The label says that the cars antifreeze is -40°C and 140°C.

so the inequality which models this situation will be -40°C < T < 140°C

Now you got to show this inequality in Fahrenheit temperature.

So the compound inequality in Fahrenheit temperature will be Option D

Answer 2

Option D is the answer.

Explanation:

The label on the car's antifreeze container claims to protect the car between -40°C and 140°C.

So inequality which models this situation will be -40°C < T < 140°C

Now we have to show this inequality in Fahrenheit temperature with the help of
`C=(5)/(9)(F-32)`

So the compound inequality in Fahrenheit temperature will be

`-40<(5)/(9)(F-32)<140`
