The time t that it takes for a group of volunteers to construct a house varies inversely as the number of volunteers v. if 20 volunteers can build a house in 62.5 working hours, how many working hours would it take 15 volunteers to build a house? round to the nearest tenth.

If 20 volunteers can build a house in 62.5 working hours, then
the job actually takes (20 x 62.5) = 1,250 volunteer-hours of work.
(That's how long it would take 1 volunteer to do the job completely
on her own.)

If there are only 15 volunteers, then they would need
(1250/15) = 83-1/3 hours to build the house, working
together.

Where the white dots are is where your points should be plotted.a translation is simply just moving something from one place to another. in this case, you would move each plot point of the original shape 2 units up, and 5 units to the left.
