Answer:
6ax+9ay−2bx−3by
Explanation:
2x(3a−b)−3y(b−3a)
Distribute:
=(2x)(3a)+(2x)(−b)+9ay+−3by
=6ax+−2bx+9ay+−3by

Answer:
$1400
Explanation:
Accumulated depreciation is the total depreciation of an asset and is recorded on the balance sheet while the depreciation expense is recorded on the income statement as an expense.
The depreciation expense is the difference between the accumulated depreciation at the end and the accumulated depreciation at the beginning. It is given as:
Depreciation expense = accumulated depreciation at the end - accumulated depreciation at the beginning = $10700 - $9300 = $1400
Depreciation expense = $1400
Answer:
a) 
b) 
c) For this case we have the total sales $ 15 millions after t =4 months
d) 
e) This value represent the increase in the amount of sales in millions after t=4 months
Explanation:
For this case we have the following function for the sales

Part a
For this case we want to find the derivate of S respect to t and we got:

Part b
For this case we want to find the value of S when t = 4 so if we replace we got:

Part c
For this case we have the total sales $ 15 millions after t =4 months
Part d
For this case we just need to replace t=4 in the derivate and we got:

Part e
This value represent the increase in the amount of sales in millions after t=4 months
