Your family is on a ski vacation. lift tickets for the family costs 80$ per day. snowboard rentals cost 40$per day. you purchase lift tickets for x days and snowboards rentals for y days and spend 480$. write an equation in standard form that represents the situation

80x+ 40y = 480

Step-by-step explanation:

Hi, to answer this question we have to write an equation in the form ax +by =C (standard form) with the information given:

The variables are:

x = number of days (tickets)

y = number of days (snowboard)

We have to multiply the price of each lift ticket per day ($80) by the number of days x, and add the product of the price of the snowboard rentals per day ($40) and the number of days y.

That expression must be equal t the total cost: $480

So, the equation is:

80x+ 40y = 480

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! : )
