Use rules of logarithms to solve the equation log(3x − 2) − log(2) = log(x + 4) [1] x = −10 [2] x = 10 [3] x = 5 [4] x = 15
Consider the following set of inequalities: y ≥ 5 − 2,5x (1) y ≤ 3 − x (2) x; y ≥ 0. (3) The correct graphical representation of this set of inequalities is given by y x (1 ) ( 2 ) y x ( 1 ) ( 2 ) y x ( 1 ) ( 2 ) y x
Questions 3 and 4 are based on the following information: The demand and supply functions for free-range chickens are Pd = 50 − 0,6Q and Ps = 20 + 0,4Q, where P is the price and Q the quantity. Question 3 The equilibrium price and quantity are [1] P = 8,00; Q = 70. [2] P = 32,00; Q = 30. [3] P = 48,50; Q = 3. [4] P = 68,00; Q = 30. 10 DSC1520/001/3 Question 4 If free-range chickens are subsidised by R4, the equilibrium price and quantity are [1] P = 17,20; Q = 3. [2] P = 29,60; Q = 34. [3] P = 34,40; Q = 26. [4] P = 84,00; Q = 170
Rewriting the equation V = 2t + 1 t − 1 with t in terms of V , gives [1] t = 6 V . [2] t = V +1 V +2 . [3] t = 1−V V −2 . [4] t = V +1 V −2 .
