Answer:
The function f(x) when x=x-4 is
or 
Step-by-step explanation:
Given function f is defined by 
Now to find the function f(x-4):

Put x=x-4 in the above function we get

(using the formula
)

(adding the like terms)


Therefore
or 
The function f(x) when x=x-4 is
or 
5+х-2+8=0
х+5-2+8=0
х+11=0
х=0-11
х=-11
The way you wrote the question was a bit confusing. Also, there are two variables here. To find the one variable (the number of rolls of wrapping paper) we need to find the number of packages.
Slope intercept form is y=mx+b
first plug in m
y=-1/2X + b
now plug in the point (8,1) for the x and the y
1=-1/2(8) + b
now you need to solve for b
simplify
1=-4+ b
add 4
5=b
now that you know b
you can plug it into the equation along with the m
so the answer is
y=-1/2X + 5
