Answer:
-560a^4b^3
Step-by-step explanation:
Given:
(2a - b)^7
By using Binomial theorem:
128a^7 - 448a^6b + 672a^5b^2 - 560a^4b^3 + 280a^3b^4 - 84a^2b^5 + 14ab^6-b^7
Here the fourth term is -560a^4b^3 !
Answer:
the answer is Y=(6/17)X + (285/17)
Step-by-step explanation:
1. Identify the X and Y coordinate of each point.
for example, the first point could be (12,21), therefore X1 = 12 and Y1 = 21 and the second point is then (46,33), therefore X2 = 46 and Y2 = 33
2. to find the equation of the line it is necessary to find the slope.
knowing that the equiation of the slope is M = Y2-Y1/X2-X1 we replace
and then we simplify the result to 
3. Using the Point-slope equation which is Y-Y1=M(X-X1) we replace

Answer:
$5,000,0000= total sales
Step-by-step explanation:
Giving the following information:
Commission rate= 4%
<u>First, we need to calculate the total commission earned:</u>
Commission= 350,000 - 125,000 - 25,000
Commission= $200,000
<u>Now, using the following formulas, we can determine the total sales:</u>
Commission= total sales*commission rate
200,000= total sales*0.04
200,000/0.04= total sales
$5,000,0000= total sales
