The price of the box of 15 stickers is $6. the price of the box of 25 stickers is $8. all prices are without tax, and the price of the boxes is the same.

write an equation which tells the price y for the number of x stickers.

y=0.2x+3

Step-by-step explanation:

Let

x> the number of stickers

y> the price

we have that

For x=15, y=6

and

For x=25, y=8

step 1

Find the slope of the linear equation

m=(8-6)/(25-15)

m=2/10=0.10 $/sticker

step 2

Find the equation of the line into point slope form

The equation of the line is equal to

y-y1=m(x-x1)

we have

m=0.10

point (15,6)

substitute

y-6=0.2(x-15)

y=0.2x-3+6

y=0.2x+3

answer: b. f(x) = (x + 2)^3 (x^2 - 7x + 3)^4

step-by-step explanation:

polynomials always have as many roots as their order. this is a 4th order polynomial- hence 4 roots!

complex roots of polynomials always come in pairs. the quadratic equation has the "+/-" in that will alwaysgenerate m+ni amd m-ni, so 7-2i must be a root of this polynomial equation.

the order of the numerator and denominator are both 2. so the horizontal asymptote is y=a2/b2 =7

verticle asymptotes are the forbidden x-values. f(x) becomes undefined at x=-3 because this value will cause a zero denominator.

a graph of r(x) will have vertical asymptotes at ±1 because these values will make the denominator zero. so the domain of the function cannot include ±1.

you 're wlecome! : )
