F(x)=2(x+10)=24
2(x+10)=24
divide 2
x+10=12
minus 10
x=2

Answer:
Find out the what is the salesman's commission as a percent of his total monthly sales .
To prove
Formula
As given
A car salesman had $65,100 in total monthly sales last month. He made $1,953 in commission from those sales.
Here
Part value = $1953
Total value = $ 65100
Put in the formula
Percentage = 3%
Therefore the salesman's commission as a percent of his total monthly sales is 3% .
Excise duty thus this type of tax is paid on goods sold
Answer: Choice A) -312,500
=====================================
The long way to find the answer is to multiply each term by -5 until you've generated 8 terms total.
4 is the first term
-20 is the second term (4 times -5 = -20)
100 is the third term (-20 times -5 = 100)
100 times -5 = -500 which is the fourth term
-500 times -5 = 2500 which is the fifth term
2500 times -5 = -12500 which is the sixth term
-12500 times -5 = 62500 which is the seventh term
62500 times -5 = -312500 which is the eigth term
---------------------
A shortcut is to use the formula below
a(n) = a*(r)^(n-1)
Plug in a = 4, r = -5 and n = 8
a(n) = a*(r)^(n-1)
a(8) = 4*(-5)^(8-1)
a(8) = 4*(-5)^7
a(8) = 4*(-78125)
a(8) = -312,500
and we get the same answer
First, find the slope of the line thru these 2 pts:
5-4
m = --------- = -1/2
2 -4
Use the slope-intercept formula y = mx + b:
5 = (-1/2)(2) + b. Then the y-intercept is 5 + 1, or 6: y = (-1/2)x + 6
Multiplying this entire result (3 terms) by 2 results in 2y = -x + 12, or
x + 2y = 12 (answer)
