Question

In countries like USA and Canada, temperature is measured in Fahrenheit, whereas in countries like India, it is measured in Celsius. Here is a linear equation that converts Fahrenheit to Celsius:
F\ =\frac{9}{5}C\ +\ 32F =
5
9
​
C + 32
If the temperature is 30°C, what is the temperature in Fahrenheit?​

Answer 1

Answer:

we need to graph of F=\frac{9}{5}

5

9

c +32

Ptting c =0

F = (9/5)0 + 32

F = 0+ 32

F = 32

So. (0,32) is a solution of the equation

putting F =0

0 = (9/5)c = -32

(9/5)c = -32

c= -32 x 5/9

= -160/9

= -17.777

So, (-160/9 , 0) is a solution of the equation
