Step-by-step explanation:
we have
-----> equation A
This is the equation of a circle with center at the origin and radius
units
-----> equation B
This is the equation of a line
we know that
The solution of the system of equations is the intersection point both graphs
using a graphing tool
The intersection points are
and ![(0,4)](https://tex.z-dn.net/?f=%280%2C4%29)
see the attached figure
therefore
the x-coordinates of the solution are
and ![0](https://tex.z-dn.net/?f=0)
Answer:
bababoi .. yay I did something
The first friend received 7 of the (7+2) = 9 total shares, or 7/9 of the money.
Answer:
We need to simplify the following expressio:
![\frac{1}{2} x^{2}- 4x-\frac{2}{x}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%20x%5E%7B2%7D-%204x-%5Cfrac%7B2%7D%7Bx%7D)
Multiply the whole expression by '2x':
![x^{3}-8x^{2}-4](https://tex.z-dn.net/?f=x%5E%7B3%7D-8x%5E%7B2%7D-4)
The expression can't be more simplified.
