- a • [- b] = c
[a] • [- b] = - c or [-a] • [b] = - c (either one is fine)
[- c] / - b = a
[- c] / [b] = - a

Answer:

Step-by-step explanation:
Average cost = total cost/number of items = (35k² + 29k + 6)/(5k + 2)
Perhaps the best way to solve this problem is to use long division.
<u> 7k + 3 </u>
5k + 2)35k² + 29k + 6
<u>35k² + 14k</u>
15k + 6
<u>15k + 6</u>
0
Thus,

The average cost per item is
.
It looks like y=x(x-2)(x+1) because of where the graph intersects the x-axis.
This is the same as y = x³-x²-2x
