When x = 2 and y = 3, z = 42. Write the function that models each of the following relationships. 1. z varies inversely with x and directly with y. z=y/x z=28y/x z=(28y)x z=3y/2x

    formula would be z = ky/x substitute: x = 2 y = 3 z = 42 formula becomes: 42 = k*3/2 solve for k to get: k = 2*42/3 = 28
