Answer:
No Solution
Step-by-step explanation:
If two lines have the same slope and different y-intercepts, that means there is no solution. If the y-intercept and the slope are the same, it will have infinite solutions... So because these have the same slope, but different y-intercepts, they won't have any solution.
Answer:
-15u+5
Step-by-step explanation:
- open up the bracket -15u-5+10
- liketerms together -15u+5
- hence answer is -15u+5
Answer:
A: 5
B: 32
C: 3
D; 14
C: 0.333
Step-by-step explanation:
A) Demand function
price (x) demand (D(x))
4 540
3.50 810
D - 540 810 - 540
----------- = -----------------
x - 4 3.50 - 4
D - 540
----------- = - 540
x - 4
D - 540 = - 540(x - 4)
D = -540x + 2160 + 540
D = 2700 - 540x
D(x) = 2700 - 540x
Revenue function, R(x)
R(x) = price * demand = x * D(x)
R(x) = x* (2700 - 540x) = 2700x - 540x^2
b) Profit, P(x)
profit = revenue - cost
P(x) = R(x) - 30
P(x) = [2700x - 540x^2] - 30
P(x) = 2700x - 540x^2 - 30
Largest possible profit => vertex of the parabola
vertex of 2700x - 540x^2 - 30
When you calculate the vertex you find x = 5 /2
=> P(x) = 3345
Answer: you should charge a log-on fee of $2.5 to have the largest profit, which is $3345.
