Chase and Oliver go to the movie theater and purchase refreshments for their friends. Chase spends a total of $40.50 on 9 drinks

Brut [27]

Answer:

The price of the drinks is $ 1.5 and the price of the bag of popcorn is $ 6.75

Step-by-step explanation:

We can solve by means of a 2x2 equation system, assuming that the question is the price of each product

We have to:

"x" price of drinks

"and" price of the bag of popcorn

9 * x + 4 * y = 40.5

3 * x + 5 * y = 38.25 => x = (38.25 - 5 * y) / 3

replacing:

9 * (38.25 - 5 * y) / 3 + 4 * y = 40.5

114.75 - 15 * y + 4 * y = 40.5

-11 * y = 40.5 - 114.75

y = -74.25 / -11

y = 6.75

now for x:

x = (38.25 - 5 * 6.75) / 3

x = 1.5

So the price of the drinks is $ 1.5 and the price of the bag of popcorn is $ 6.75

Select the correct answer

Paladinen [302]

Answer:

a) We get $\mathbf{A+B=x^2-2x+1}$

So, Is the result of A+B is a polynomial:Yes

b) We get $\mathbf{A-B=6x^3-7x^2+2x-1}$

So, Is the result of A-B is a polynomial:Yes

c) We get $\mathbf{A.B=9x^6+21x^5-18x^4+9x^3-3x^2}$

So, Is the result of A.B is a polynomial:Yes

Step-by-step explanation:

We are giving the polynomial equations:

$A= 3x^2(x-1)\\B=-3x^3+4x^2-2x+1$

We need to find

a) A+B

$A+B=3x^2(x-1)+(-3x^3+4x^2-2x+1)\\A+B=3x^3-3x^2-3x^3+4x^2-2x+1\\A+B=3x^3-3x^3-3x^2+4x^2-2x+1\\A+B=x^2-2x+1\\$

So, we get $\mathbf{A+B=x^2-2x+1}$

So, Is the result of A+B is a polynomial:Yes

b) A-B

$A-B=3x^2(x-1)-(-3x^3+4x^2-2x+1)\\A-B=3x^3-3x^2+3x^3-4x^2+2x-1\\A-B=3x^3+3x^3-3x^2-4x^2+2x-1\\A-B=6x^3-7x^2+2x-1\\$

So, we get $\mathbf{A-B=6x^3-7x^2+2x-1}$

So, Is the result of A-B is a polynomial:Yes

c) A . B

$A.B=3x^3(-3x^3+4x^2-2x+1)-3x^2(-3x^3+4x^2-2x+1)\\A.B=9x^6+12x^5-6x^4+3x^3+9x^5-12x^4+6x^3-3x^2\\A.B=9x^6+12x^5+9x^5-6x^4-12x^4+3x^3+6x^3-3x^2\\A.B=9x^6+21x^5-18x^4+9x^3-3x^2$

So, we get $\mathbf{A.B=9x^6+21x^5-18x^4+9x^3-3x^2}$

So, Is the result of A.B is a polynomial:Yes
