A) \[(0,\,3/2)\]
B) \[\left( 1/2,\,3/2 \right]\]
C) \[\left[ 1/2,\,3/2 \right)\]
D) \[\left[ 0,\,1/2 \right)\]
Correct Answer: B
Solution :
[b] \[6\le -3(2x-5)<12\] \[\Rightarrow 2\le -(2x-5)<4\] \[\Rightarrow -2\ge 2x-5>-4\] \[\Rightarrow 5-2\ge 2x>5-4\] \[\Rightarrow 3\ge 2x>1\] \[\Rightarrow 3/2\ge x>1/2\] Thus, the solution set for the given inequality is (1/2, 3/2].You need to login to perform this action.
