Machine 1 can complete a task in x hours while an upgraded machine (machine 2) needs 9 fewer hours. The plant manager knows the two machines will take at least 6 hours, as represented by the inequality:
1/x+1/x-9 more than or equal to 1/6
Which answer choice includes all solutions to the inequality and identifies which interval(s) contain viable completion times of
machine 1?
