The math club is doing a fundraiser to raise money to attend a math competition. the club was told by their advisor to raise $2000, but they decided to raise $4000. the club is selling " i like tt" t-shirts for $10 and "i like tt" sweaters for $20. let x equal the number of t-shirts sold and let y equal the number of sweatshirts sold. are the graphs of the equations parallel and how can you tell?

number of t-shirts are represented by 't'  

number of sweaters are represented by 's'

Step-by-step explanation:cost of 1t=10 and cost of 1s=20 so

10t+20s=2000 or (factor out the 10 if you optate to simplify)

10(t+2s)=10(200)

divide both sides by 2

t+2s=200

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! : )
