2. Suppose that y varies directly with x and inversely with z, and y = 18 when x = 15 and z = 5. Write the equation that models the relationship. Then find y when x = 21 and z = 7. (1 point) Connections help????

Best ResponseYou've already chosen the best response.3for variation problems, you must first find the constant. the formula for direct variation is Y = KX formula for inverse variation is Y = k/Z so combine the two based on your problem Y = (KX)/Z plug in given values for y x and z to find k tell me what K is

Best ResponseYou've already chosen the best response.3now using that value of k use the same formula and solve for Y based on that x = 21 and z = 7 what did you get?
