Question 83635: The solutions of line m are (3, 3), (5, 5), (15, 15), (34, 34), (678, 678), and (1234, 1234).
The solutions of line n are (3, -3), (5, -5), (15, -15), (34, -34), (678, -678), and (1234, -1234).
Form the equations of both the lines.
What are the co-ordinates of the point of intersection of lines m and n?
Write the co-ordinates of the intersections of lines m and n with the x-axis.
Write the co-ordinates of the intersection of lines m and n with the y-axis.
Thank You

Question 83855: This seems pretty easy, but I'm a little confused with this question:
There is $3.50 in nickels and dimes, if there are already 50 coins; how many of each type of coin is there?
A coffee merchant has coffee beans that sell for $9 per pound and $12 per pound. The two types are mixed to create 100lb of a mixture that will sell for $11.25 per pound. How much of each type of bean should be used in the mixture?
Also if I could and explanation on how I would figure out how to decide how much of each bean should be used.
Thank you for any help that I can get.

Question 84625: The supply equation is Y= 28X + 2025 and the demand equation is Y= -17X + 6120. The equilibrium demand is
A. 45
B. 4573
C. 2025
D. 91
I figured this problem and came up with the values of X = 91 and Y = 4573. Both of these answers are listed above. Which one is the equilibrium demand?, or do I have to continue figuring further to get another answer?? PLEASE assist.

Question 84803: 2) In most businesses, increasing prices of products can negatively impact the number of customers. A bus company in a small town has an average number of riders of 800 per day. The bus company charges $2.25 for a ride. They conducted a survey of their customers and found that they will lose approximately 40 customers per day for each $.25 increase in fare.
a) Let the number of riders be a function of the fare charged. Graph the function, identify the graph of the function (line, parabola, hyperbola, or exponential), and find the slope of the graph.
b) The bus company has determined that even if they set the price very low, there is a maximum number of riders permitted each day. If the price is $0 (free), how many riders are permitted each day?
c) If the bus company sets the price too high, no one will be willing to ride the bus. Beginning at what ticket price will no one be willing to ride the bus?
