Scenario 1: The cook at Sam's Diner made 19 quiches today. This is 1 more than 3 times the number of quiches he
made yesterday. How many quiches did he make yesterday?
Scenario 2: Javier buys four dozen eggs. He saves $1.50 by
using a coupon. The total he pays is $8.50. What was the
cost of a dozen eggs without the coupon?
Scenario 3: Lina ate of a quiche for lunch. Each of her
two sisters split another piece equally. The three ate a total
of of the quiche. What fraction of the quiche did each of
Lina's sisters eat?

i dont know sorry

step-by-step explanation:

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! : )

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
