Machine 1 can complete a task in x hours while an upgraded machine (machine 2) needs 9 fewer hours. The plant mana

knows the two machines will take at least 6 hours, as represented by the inequality

Which answer choice includes all solutions to the inequality and identifies which interval (s) contain viable completion time

machine 12

(0.31 U 9.18] both contain viable times for machine 1

(0 3] U9,18]; only (9.18) contains viable times for machine 1

(-00U13,9 UL18, co), no interval contains viable times for machine 1

(-0,0) U (39) U (18, co), but only [18,00) contains viable times for machine 1
