Bess visited a library that had floors above ground level. The library also had floors below ground. While visiting the library, Bess entered on the ground level, went to both the third and fourth floor above ground, returned to the ground- level floor, and then went to the third floor below ground. When she finished, she returned to the ground level. Which set of integers best represents the floors Bess visited at the library.

i think this could be a possible answer (1 / 84) -1

good luck! : d

step-by-step explanation:

you are throwing one dart

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
