A new gaming system at Gamestop is sold for $500.00. It costs the manufacturer of the system $490 to make it. Use this information to help solve 1a, 1b, and 1c. 1a. Write and solve an equation to determine what the percent markup is.

1b. Upon purchasing the unit you will also need to pay 7.5% sales tax, write and solve an equation to determine what the final purchase price will be.
1c. Gamestop is providing their employees with a bonus of 13% commission for everything they sell this weekend. Write and solve an equation to determine what the final purchase price will be.

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! : )

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4

too hard the other guy did it
