QUESTION 16 Simplify: (cos x) (csc x) (tan x) = O A. sin x cos x O B. 1 OC.2 OD. sin2 x cos x QUESTION 17 Use the Elimination method to solve the system x 2 - 2y = - 1 x2 + 5y = 34 The two solutions of the system for x 0 are: O A. X = 3, y = 5 and y = -3 and x = -5 O B. x = 3, y = -5 and y = -3 and x = 5 O C. x = -3, y = 5 and x = 3, y = 5 O D.x = -3, y = -5 and x = 3,y= -5
