Answer:

C.

Step-by-step explanation:

I did the division process in the picture below. The result can be viewed as

\frac{x^2+17x+63}{x+8} = (x+9)(x+8) -9. Then, the result is x+9 and the remainder is -9.

Tom [10]

Answer:

Discount is $2.70

After-discount price is $15.30

Step-by-step explanation:

To get the after-discount price, multiply $18 by (1.00 - 0.15), or, in other words, multiply $18 by 0.85.  The after-discount price is $15.30.

Two ways to find the discount:  one is to multiply $18 by 0.15; the other way is to subtract $15.30 from $18.

A company produces two types of solar panels per year: x thousand of type A and y thousand of type B. The revenue and cost equat
jolli1 [7]

Answer:

  • 7000 type A
  • 6000 type B

Step-by-step explanation:

We assume your equations are intended to be ...

C(x,y)=x^2-2xy+9y^2+3x-87y-6\\R(x,y)=5x+7y

Then the profit equation is ...

P(x,y)=R(x,y)-C(x,y)=5x+7y-x^2+2xy-9y^2-3x+87y+6\\=-x^2+2xy-9y^2+2x+94y+6

The partial derivatives of profit with respect to x and y are zero when profit is maximized.

  ∂P/∂x = 0 = -2x +2y +2

  ∂P/∂y = 0 = 2x -18y +94

Simplifying, these equations are ...

  • y = x -1
  • x -9y = -47

Substituting the first into the second gives ...

  x -9(x -1) = -47

  -8x = -56

  x = 7

  y = 7 -1 = 6

The company will maximize profit by selling 7000 panels of type A and 6000 panels of type B.
