Question 1068758: How do I find all values of x for which f(x)>g(x) and when f(x)
The temperature in degrees Celsius (C) can be converted to degrees Fahrenheit (F) using the formula F(C)= 9/5 C+k, where k is a constant. Find k, if to C=−40C corresponds F=−40F.

You can put this solution on YOUR website!
You can graph them and look for intersection points and then judge which is greater in that interval.

-40=%289%2F5%29%28-40%29%2Bk
k=-40%2B40%289%2F5%29
k=40%289%2F5-1%29
k=40%289%2F5-5%2F5%29
k=40%284%2F5%29
k=32
