What element in domain ha image 25/9 under function f(x)= 4x+5/x+4

First I'll make the assumption that you mean

          4x+5

f(x) =

            x+4

and then set this function = to 25/9:

          4x+5         25

f(x) = =

            x+4           9

Solve for x:  Cross-multiplying, we get 36x + 45 = 25x + 100.

Consolidating like terms, we get 11x = 55.  Thus, x = 5.

x = 5

equate f(x) =

= → (cross- multiply)

9(4x + 5) = 25(x + 4) → (distribute both sides )

36x + 45 = 25x + 100 → ( subtract 25x from both sides )

11x + 45 = 100 → ( subtract 45 from both sides )

11x = 55 → ( divide both sides by 11 )

x = = 5

don't know what that says sorry i can't you
