Question

the function 't' which maps temperature in Celsius (c) into temperature in Fahrenheit (f) is defined by t(c) = f where f =9÷5c+32 find the temperature when c=f​

Answer 1

Answer:

-40°C=-40°F

Step-by-step explanation:

Given that,

C=F.

F=9/5F+32

F-32=9/5F

5F-160=9F

-160=4F

F=-160/4

F=-40
