The (0, 3] is taken out of the picture leaving you with B.
We have given that,
Machine 1 can complete a task in x hours while an upgraded machine (machine 2) needs 9 fewer hours.
We have to determine the,
The plant manager knows the two machines will take at least 6 hours, as represented by the inequality
after you find the intervals.
you also need to consider that the plant manager knows the two machines will take at least 6 hours.
so (0, 3] is taken out of the picture leaving you with B.

Answer:
See Explanation
Step-by-step explanation:
The question has missing details. So, I'll solve using a general assumption.
Let one of the coordinates of the figure be
Let the scale factor be n
When dilated, the new figure is:
To return the image back to the original figure, the new scale factor mus be a reciprocal of the previous scale factor i.e. 
So:
Substitute n(x,y) for A';
Take for instance:
-- scale factor
To get A from A', using the analysis above
