Answer:

Step-by-step explanation:

Y=9x²+12x+4

Y=9(x²+(12/9)x+4/9)

Y=9(x²+(4/3)x+4/9)

Y=9(x²+2(2/3)x+4/9)

Y=9(x²+2(2/3)x+4/9)

Y=9(x+2/3)²

Y = 0 : x+2/3 = 0

x = -2/3 is the solution of a polynomial

Mrs. Julien’s and Mrs. Castillejo’s classes are selling cookie dough for a school fundraiser. Customers can buy packages of maca
Oksi-84 [34.3K]

Answer: the cost of one package of macadamia nut chip cookie dough is $1.5

the cost of one package of triple chocolate cookie dough is $2.5

Step-by-step explanation:

Let x represent the cost of one package of macadamia nut chip cookie dough.

Let y represent the cost of one package of triple chocolate cookie dough.

Mrs. Julien’s class sold 25 packages of macadamia nut chip cookie dough and 30 packages of triple chocolate cookie dough for a total of $112.50. This means that

25x + 30y = 112.5 - - - - - - - - - - - - -1

Mrs. Castillejo’s class sold 8 packages of macadamia nut chip cookie dough and 45 packages of triple chocolate cookie dough for a total of $124.50. This means that

8x + 45y = 124.5 - - - - - - - - - - -2

Multiplying equation 1 by 8 and equation 2 by 25, it becomes

200x + 240y = 900

200x + 1125 = 3112.5

Subtracting, it becomes

- 885y = - 2212.5

y = - 2212.5/- 885

y = 2.5

Substituting y = 2.5 into equation 1, it becomes

25x + 30 × 2.5 = 112.5

25x + 75 = 112.5

25x = 112.5 - 75 = 37.5

x = 37.5/25 = 1.5

The method used is the elimination method. It is more convenient to use.

navik [9.2K]

The real is B.) f(x) = -x + 11

A.) f(x) = -y + 11 is the wrong answer.

I have pictures to prove that they are the same in the graph as x + y = 11.

Hope this will help a lot more than the other answer.
