An inverse function produces points (y,x) for every point (x,y) produced by the parent function. So to find the inverse function, you solve for the independent variable and when done switch the variable labels....
y=x+5 subtract 5 from both sides
y-5=x now switch labels
y=x-5
So if f(x)=x+5
f^-1(x)=x-5
The answer is (1,1) since that is where J and K intersect.
In equations like this, you could use PEMDAS- Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction in that order. Since there are no parentheses or exponents you can go to multiplication. Since x=9 and y=6, you multiply x(9) and y(6) to get 54. Now you can add since there is no division or subtraction involved. 54+ u(2) = 56. So u + xy = B. 56
