Read each problem situation and use the different representations
to answer the questions.
y - 12x = 100
1. charlie is an avid reader and purchases e-books. for his
birthday, his grandparents want to enroll him in a book of the
month club. they plan to purchase a $100 gift certificate to
the e-book club. in their research, they found two plans with
comparable book offerings.
readers-r-us automatically loads the book of the month
onto the e-reader at the beginning of each month, and for
this service, the club charges each member $4.50 per month.
consider an equation in which y represents the amount of
money remaining in charles's account and is expressed as a
function of the number of months charlie is a member.
a second company, bookworms, presents the table shown to
illustrate their plan, given a purchase of a $100 gift certificate.

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

we have the parent function given by,

1. the function is translated 5 units to the left.

so, we get,   becomes

2. the function is translated 5 units to the right.

so, we get,   becomes

3. the function is translated 5 units upwards.

so, we get,   becomes

4. the function is translated 5 units downwards.

so, we get,   becomes

5. the function is reflected across x-axis.

so, we get,   becomes

6. the function is reflected across y-axis.

so, we get,   becomes .
