Answer: Company A would be a better deal for number of minutes over 200
Step-by-step explanation:
Let x represent the number of minutes that you would use with either company A or company B.
Company A has a monthly charge of $10 plus 5¢ a minute for each minute of long distance calls. It means that the cost of x minutes of long distance call is
10 + 0.05x
Company B has a monthly charge of $8 plus 6¢ a minute for long distance calls. It means that the cost of x minutes of long distance call is 10 + 0.05x
8 + 0.06x
For Company A to be a better deal, it means that
10 + 0.05x < 8 + 0.06x
10 - 8 < 0.06x - 0.05x
2 < 0.01x
0.01x > 2
x > 2/0.01
x > 200

Answer:
A = -68.75p +2906.25
Step-by-step explanation:
We can solve for m and b using the given values of A and p.
1600 = m·19 +b
2150 = m·11 +b
Subtracting the second equation from the first, we have ...
-550 = 8m
m = -550/8 = -68.75
Substituting this into the first equation gives ...
1600 = 19·(-68.75) +b
b = 1600 +1306.25 = 2906.25
The desired linear equation is ...
A = -68.75p +2906.25

<em>Additional comment</em>
Revenue will be maximized at the price that cuts attendance to half the value when the price is 0, about $21.14.
Here we are going to use the equation y=15x2+3x+56.
x=0 in 2,000 so x=10 in 2010.
Substitute 10 for x.
After this we have the answer: D. $1,586
Answer:
option 3
Step-by-step explanation:
sin45° = 11/BC
=>1/√2 = 11/BC
=>BC = 11√2
Answer:
The slope is 1
Step-by-step explanation:
Lets pick two points on the line
(0,1) and (-1,0)
We can use the slope equation
m = (y2-y1)/(x2-x1)
= (0-1)/(-1 -0)
=-1/-1
=1
