If f(X)= 7x +5/3 - x =6x +5/3
y= 6x +5/3
6x= y-5/3
f^-1(y)=x=(y-5/3)/6
So we can write
f(f^-1(y))= f((y-5/3)/6) = 6 (y-5/3)/6 +5/3= y-5/3+5/3= y
The same result can be obtained for f^-1(f(x))=x
If the function is f(x)= 7x +5/(3-x) then it is not invertible since it is not injective (pictures)
37k (cost of the materials for each kite) plus 28k (the labor for each kite) plus 6,000=x (the total cost). With this equation you can plug in any number of kites so...
37k+28k+6,000=x Combine like terms...
65k+6,000=x Plug in k...
65(170)+6,000=x Multiply...
11,050+6,000=x Add...
x=17,050

I would be happy to answer but you need to attach a question.
The identity property shows us that any number that adds zero to itself stays itself. The identity for multiplication tells us that any number multiplied by one is itself.
