Um professor de matemática apresentou a sua turma o seguinte problema para ser resolvido. Jéssica ganhou uma barra de chocolate de 200g e comeu 2/4 dessa Barra no mesmo dia. Quantos gramas de chocolate dessa barra Jéssica comeu nesse dia?

-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

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.

answer:

125 yards

explanation:

75+50=125. that is my answer

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:
