Question 70609: 2) In most businesses, increasing prices of their product can have a negative effect on the number of customers of the business. A bus company in a small town has an average number of riders of 1,000 per day. The bus company charges $2.00 for a ride. They conducted a survey of their customers and found that they will lose approximately 50 customers per day for each $.25 increase in fare.
a) Given the description above, graph the function, identify the graph of the function (line, parabola, hyperbola, or exponential), find the slope of the graph, find the price at which there will be no more riders, and find the maximum number of riders possible. The vertical axis is the number of riders per day, and the horizontal axis is the fare.
Graph:
Graph Type:
What is 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?

Question 70779This question is from textbook 
: I have a simple question. (My memory seems blocked right now)
1/3x > -5 -1/2x
My next step would be to add 1/2x to both sides?
add 1/2 to both sides?
multiply -2/1x to both sides?
multiply -2/1 to both sides?
Please refresh my memory on this one.This question is from textbook

Question 70979: I am working on a test review sheet from my professor and having trouble with one of the problems. We are studying inequalities in 2 variables and graphing. Here is the problem...Graph 7x > 3y. I have tried dividing both sides by 3 and adding -3y to both sides, but I must be in the middle of a brain fog and can not figure it out. Any help would be GREATLY appreciated.
Thanks,
Yvonne

Question 71193: Let x=rate invested at 5%.
Then the rate invested at 2% is 25,000-x
You have: 0.05x+0.02(25,000-x)=980
0.05x+500-0.02x=980
0.03x+500=980
0.03x=480
x=16000
$16,000 was invested at 5% and 9,000 at 2%.

Question 71008: Solve the following systems by addition. If a unique soution does not exist, state whether the system is inconsistent or dependent.
The idea is to multiply a row by something so that when it's added to the other row a variable is eliminated. In this case, multiply the top row by -5 and the bottom row by 2.
Add and eliminate x:
