Question 140421: a. Suppose that a market research company finds that at a price of p = $20, they would sell x = 42 tiles each month. If they lower the price to p = $10, then more people would purchase the tile, and they can expect to sell x = 52 tiles in a month’s time. Find the equation of the line for the demand equation. Write your answer in the form p = mx + b. (Hint: Write an equation using two points in the form (x,p)).

Question 140432: Graph each of the following equations:
x^2+y^=5
x+y=1
Use the graph to approximate their intersection. Use algebra to find the exact coordinates of intersection.
Since both variables have the same exponent. Would this not be a circle? Just curious.. Thankyou Maria

Question 140674: I need some assistance, please show me how to graph this equation.
4x-1=3x+15
This is the formula that I came up with in answer to a word problem. I worked it out and came up with x=16. I then graphed it as a strait line by coming up with various points for y. The problem was sent back as needing to be revised. The equation and answer was fine. This is the comment they made:
The algebraic solution is correct.
To solve the equation graphically, notice that it is made up of two functions, y=4x-1 and y=3x+15.
The solution is at the intersection of these two lines.
Be sure to show the intersection on the graph.
Can anyone tell me how to do this, there are more problems like this coming up and I want to get them right the first time.

Question 140719: Need assistance with a complex problem.
The director of a summer day camp estimates that 100 children will join if the camp fee is $250, but for each $20 decrease in the fee, ten more children will enroll. Determine the linear equation that will represent the number of children who will enroll at a given fee. Hint: To write the slope, you need two points on the line. Show all work to receive full credit. Graph the linear equation that represents the number of children who will enroll at a given fee.
Approximately how many students will enroll if the camp fee is $180? Round to the nearest child. Show all work for full credit. Approximately how many students will enroll if the camp is free?
I would be greatful for any assistance with this complexed problem.

Question 140709: What similarities and differences do you see between functions and linear equations? Are all linear equations functions? Is there an instance when a linear equation is not a function?
The only similarities that I can find is that linear equations and functions have a x axis and an y axis. I have also found that not all linear equations are functions. I can not find anything about differences or an instance when a linear equation is not a function.
