Asked by Johannes
                Y varies partly as x, partly inversely as x and partly constant. The graph of y against x passes through the points (2,20), (3,16), and (5,14). Find a general formula for y in terms of x
My proposed formula is
y = x / kx
            
        My proposed formula is
y = x / kx

    Your equation just satisfies y varies directly as x. What about the rest?
y = ax + b/x + c
Now use the points to get 3 equations in a,b,c and solve them.
