Lesson 1: DIRECT VARIATION Solve for the unknown value assuming that y varies directly as X.
a. If y = 8 when x = 4, what is the value of Y when x = 3 10? -12, what is the value of Ywhen x = 24? = 2 when x = 4, what is the value of Ywhen x = -8? 3 5 when x = 10, what is the value of Ywben x = 30? when x = -12, what is the value of Ywhen x = -8? 2. Solve the problem using the process of direct variation If 2 kg of rice costs P96, how much is 8 kg of rice? b. A 20-meter tree casts a 12-meter shadow, how tall is the tree that casts 16meter shadow? Lesson 2: INVERSE VARIATION Answer the following. m varies inversely as n. If m = 4 when n = 3, find m when n = 7. b a varies inversely as b. If a = 11 when b = 6, find the value of a when b = 9. y varies inversely as x. If y =
