Please use "^" to denote exponentiation:  f(x) = x^2 - 6x.

To find f(-a), replace "x" with "(-a)" in the function (x) = x^2 - 6x:

f(-a) = (-a)^2 - 6(-a)  =  a^2 + 6a (answer)

Rus_ich [418]

Answer:

22500 units

Step-by-step explanation:

Ending inventory =. 3000

Beginning inventory = 2500

Good sold = 22000

Beginning inventory + budgeted purchases - goods sold = ending inventory

2500 + x - 22000 = 3000

2500 + x = 3000 + 22000

2500 + x = 25000

x =25000 - 2500

x = 22500 units

amid [387]

Answer:

Step-by-step explanation:

-3x^3 - 2x^2 - x -2 divided by x - 2 using long division:

          -3x^2 - 8x - 17

x - 2    -3x^3 - 2x^2 - x -2

           -3x^3 + 6x^2

                     - 8x^2 - x

                     -8x^2 + 16x

                                 -17x - 2

                                 -17x + 34

                                          -36

So -3x^3 - 2x^2 - x -2 divided by x - 2:

quotient is    -3x^2 - 8x - 17 with a reminder of      -36
