The inverse of F(C)=9/5C+32

Nataliya [291]

F(C) = 9/5C + 32

I'll just change F(C) to y and 9/5C to 9/5x.
y = 9/5x + 32

inverse...

x = 9/5y + 32
9/5y = x - 32
y = 5/9x - 160/9

Sooooo
F(C) = 5/9C - 160/9

Answer:

$y = \sqrt[5]{50}$

Step-by-step explanation:

$25 + 25 = {y}^{5}$

${y}^{5} = 25 + 25$

${y}^{5} = 50$

Take the 5th root of both sides of the equation to eliminate the exponent on the left side.

$y = \sqrt[5]{50}$
