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 .
Answer:
Domain: -5 x < 1
Range: -4 y < 7
Step-by-step explanation:
The domain is the x-values for which the function exists. It starts off at x=-5, and since the dot is closed it includes it, and finishes at x = 1, where the dot is open.
The range is the y-values for which the function exists. It starts at y= -4, and since the dot is closed there, it includes his value. Then, it finishes at y = 7, where the dot is open meaning it doesn't include it.
