Answer:
20-2(n-1)
Step-by-step explanation:
The general term (or the nth term) of this sequence is [20-2(n-1)].
Verification:
1st term = 20-2(1-1) = 20-2(0) = 20-0 = 20
2nd term = 20-2(2-1) = 20-2(1) = 20-2 = 18
3rd term = 20-2(3-1) = 20-2(2) = 20-4 = 16
4th term = 20-2(4-1) = 20-2(3) = 20-6 = 14
A) intercepts: zero profit; maximum: maximum profit. increasing: x < 4; decreasing x > 4
B) average slope: ≈50, about $50 increased profit for each $1 increase in price.

Answer:
x = 2
Step-by-step explanation:
-3 +6x = 25 -8x
Add 8x to each side
-3 +6x+8x = 25 -8x=8x
-3+14x = 25
Add 3 to each side
-3+3+14x = 25+3
14x = 28
Divide by 14
14x/14 = 28/14
x = 2
