Naomi is a songwriter who collects royalties on her songs whenever they are played in
a commercial or a movie. Naomi will earn $20 every time one of her songs is played
in a commercial and she will earn $100 every time one of her songs is played in a
movie. Naomi's songs were played on 3 more commercials than movies, and her total
earnings on the royalties from all commercials and movies was $300. Graphically
solve a system of equations in order to determine the number of commercials, I, and
the number of movies, y, on which Naomi's songs were played.

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

the battle of gettysburg is considered the "high water mark" of the confederacy because it marked the greatest advance of the confederate forces against the union.
