Inequalities Part-2
06) If | x + (1/4)| > (7/4), then : (a) x < -3 or x > 2 2 (b) x < -2 or x > 3 2 (c) -2 < x < 3 2 (d) None of these
07) The shaded region represents:
(a) 3x + 5y < 15, 5x + 2y > 10,x,y >0 (b) 3x + 5y < 15, 5x + 2y < 10,x,y >0 (c)3x + 5y >15, 5x + 2y > 10,x,y >0
08) If a > 0 and b<0, Ii follow that: (a) (1/a) > (1/b) (b) (1/a) < (1/b) (c) (1/a) = (1/b) (d) None of these
09) On solving the inequalities 6x + y > 18, x + 4y > 12, 2x + y > 10, we get the following situation : (a) (0, 18), (12, 0), (4, 2), (7, 6) (b) (3, 0), (0, 3), (4, 2), (7, 6) (c) (5, 0), (0, 10), (4, 2), (7, 6) (d) (0, 18), (12, 0), (4, 2) , (0, 0) and (7, 6)
