Suppose that y varies inversely with x, and y= 3 when x = 10. (a) Write an inverse variation equation that relates x and y.
Equation:
(b) Find y when x = 5
y =

Given that y varies directly to the square root of (x + 1), and that y = 1 when x = 8,(a)express y in terms of .x,(b)find the value of y when x = 3,(c)find the value of x when y = 5.
