Cassie is making greeting cards, which she will sell by the box at an arts fair. She paid $32 for a booth at the fair, and the materials for each box of cards cost $7. She will sell the cards
for $9 per box of cards. At some point, she will sell enough cards so that her sales cover her
expenditures. How many cards will that take? How much will the sales and expenditures be?

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

damm bro the struggle

step-by-step explanation:

you can't solve x because it is 2 linear equation and you only have one equation

answer:

a=9
