The solution to a system of (linear) equations is the point where the graphs intersect. Consider two parallel lines. By definition, two parallel lines never intersect each other, but all pairs of non-parallel lines will eventually intersect. That means they will also have a solution.
Let's consider what makes a line parallel to another line. It basically looks identical, having the same steepness (slope), but the graph is just shifted over. That is, a parallel line would have the same slope and a different y-intercept. For our equation
, or
in slope-intercept form, a parallel line will be of the form
.
That describes the form of a parallel line, which we do not want. Any other line, however, will give a solution to our system, so we merely want a line where the slope does not equal 2.
We can have any equation of the form
.
Heya!!!
Answer to your question:
Let Adam's points be x.
Nick has points =7200=20%of x+x
20/100 *x + x=7200
x/5 +x=7200
6x/5=7200
x= 7200*5/6
x=6000
Adam has 6,000 points.
Hope it helps *_*

Answer:
1. The value 40÷40.01 is close to 1.
2. The value 4÷40.01 is much less than 1.
3. The value 4000÷40.01 is greater than 1.
Step-by-step explanation:
The given numbers are 4, 40 and 4000.
Divide each number 4, 40 and 4000 by 40.01 we get
The value __40___÷40.01 is close to 1.
The value __4___÷40.01 is much less than 1
The value __4000___÷40.01 is greater than 1.
