Calculate Matthew's Income: Calculate Matthew's Expenses:
$10.75 an hour x 18 hours = $ 193.50 a week
Rent = $450.00
$193.50 x 2 weeks = $387.00 per paycheck
Groceries = $200.00
$387.00 - 10% = $348.30
Phone, Internet and Cable = $175.00
$348.30 x 2 paychecks a month = $696.60 a month
Monthly Income =
Monthly Expenses =

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
