The label on the car's antifreeze container claims to protect the car between −40°C and 125°C. To convert Celsius temperature to Fahrenheit temperature, the formula is C = 5/9 (F − 32). Write and solve the inequality to determine the Fahrenheit temperature range at which this antifreeze protects the car. (2 points)



−40 > 5/9 (F − 32) > 125; −40 > F > 257

−40 < 5/9 (F − 32) < 125; −40 < F < 257

−40 < 5/9 (F − 32); −40 < F

5/9 (F − 32) < 125; F < 257

Answer 1

Answer 2

You need to change your given equation so that you can find the degrees fahrenheit.
C = 5/9 (F − 32)
F = 9/5C +32

So...

((9/5 x -40°C) +32) < °F < ((9/5 x 125°C) + 32)

Answer 3

You'll need to simplify the right side of the inequality to find your answer.

Answer 4

This right side, simplify this? > 9/5 x 125°C) + 32

Answer 5

Yes.

Answer 6

\[9/5x ^{125} + 32\]

Answer 7

Is this the answer ^ @Aveline
