Identify which is a solution of the inequality x7x2 greatert
     Identify which is a solution of the inequality  x+7/x-2 greaterthanorequalto 0  Select one:  2  -1  -10  -2  None of the above 
  
  Solution
(x+7)/(x-2)>=0
testing points x=-7 , 2
testing regions
(- infinity,-7) ,(-7,2),(2,infinity)
and on taking x=-10 we will get
-3/-5=3/5>0
therefore the correct option is c.
