If f(x)=(5x-1)/9 Then the inverse is x=(5y-1)/9 9x=5y-1 9x+1=5y (9x+1)/5=y The inverse is f(x)=(9x+1)/5
If: 5x/10 = 2 then the value of x works out as 4
Multiply the bottom equation by -1
It is: y = -1/5x-2
y = 5x + 9

If f(x)=(5x-1)/9 Then the inverse is x=(5y-1)/9 9x=5y-1 9x+1=5y (9x+1)/5=y The inverse is f(x)=(9x+1)/5
5x = 80
If: 5x/10 = 2 then the value of x works out as 4
If the equation is (5x + 3 - 7) / 2 = 56, than x = 23.2
y = 5x + 1 y - 1 = 5x (y - 1) / 5 = x
No, f(x) is not the inverse of f(x).

y=6/5x is a rational function not a line.
5x-4y=8
