Since x & y vary directly (it means when x increases, y increases & vice versa)
Then the equation==> y = k.x (k is a constant to be calculated)
But x=4 and y= (given) ==> 2=4k or k= 1/2 & the equation becomes <span>y=1/2 (x)</span>

Answer: The freezing temperature of water in degrees Fahrenheit is 32.
Step-by-step explanation:
Hi, to answer this question we have to replace the value of the variable "C" in the formula F(C), by the value given in Celsius that water freezes.
Mathematically speaking:
F(C) = 32 +1.8 C
F (0) = 32 +1.8 (0)
Solving for F (Fahrenheit), since any number multiplied by zero equals zero:
F = 32
The freezing temperature of water in degrees Fahrenheit is 32.
