Answer:

(24, -15)

Step-by-step explanation:

-3x + 4y = 12

3x – 6y = 18

Add the two equations together to first solve for y

-2y=30

y=-15

Enter -15 into one of the equations to solve for x

-3x + 4(-15) = 12

-3x-60=12

-3x=72

x=24

What is the product?

svlad2 [7]

Answer:

Third option: 2x^3-11x^2+16x-3

Step-by-step explanation:

The product to be found is:

$(x-3)(2x^2-5x+1)$

Distributive property will be used for the product:

$x(2x^2-5x+1)-3(2x^2-5x+1)\\$

Multiplication will give us:

$=2x^3-5x^2+x-6x^2+15x-3\\Combining\ alike\ terms\\=2x^3-5x^2-6x^2+x+15x-3\\=2x^3-11x^2+16x-3$

The product is: 2x^3-11x^2+16x-3

Hence, third option is the correct answer ..
