The solution of a system of linear equations is where the two lines intersect....

Answer:
Step-by-step explanation:
True.
There is only 1 intersection point. That is the point where the x and y values are the same for both equations. For example if you have
y = 2x + 5 and
y = 3x + 2
The intersect point is (3,11). If you put 3 in each equation for x, they will return 11 for the y value.
I've included a graph to show you that this is true.

We have that
<span>p(t)=-3t^2+18t-4
using a graphing tool, we can see the maximum of the graph
(see the attached figure)
A) </span><span>In what year of operation does Mr. Cash’s business show maximum profit?
</span>Mr. Cash’s business show maximum profit at year 3 (maximum in the parabole)
<span>B) What is the maximum profit?
23 (hundred of thousand of dollars) = 2.300.000 dollars
</span>c) What time will it be two late?
(This is the time when the graph crosses zero and the profits turn into losses )
5.77 years, or an estimate of about 69 months.
