Given the equation F=9/5C+32, where C is the temperature in degrees Celsius and F is the corresponding temperature in degrees Fahrenheit,
and the following ordered pairs:(5,F1), (−25,F2)
Compute the missing y values so that each ordered pair will satisfy the given equation.
~~~~~~~~~~~~~~~~~~
Consider first pair (5,F1).
In this pair, 5 is the argument "C" of the given function, and F1 is the value of the given function, corresponding to argument C= 5.
In other words, C= 5 is the given Celsius temperature, and they want you find the corresponding Fahrenheit temperature.
To do it, you simply substitute the value of C= 5 into the given formula and compute Fahrenheit temperature
= 9 + 32 = 41.
It is your ANSWER : Fahrenheit temperature F1 is F1 = 41 F.
Solved.
