Answer:
The answer would be 7mn^5 - 2m^6 + 14m^2n^4 - 5m^3n^3 + n^6
Step-by-step explanation:
In order to find that answer, start by grouping all of the terms by their variable values. Ones that are the same should be combined.
8mn^5 - mn^5 = 7mn^5
2m^6 - 4m^6 = -2m^6
5m^2n^4 + 9m^2n^4 = 14m^2n^4
-m^3n^3 - 4m^3n^3 = -5m^3n^3
n^6 = n^6
Now we simply combine them all to get
7mn^5 - 2m^6 + 14m^2n^4 - 5m^3n^3 + n^6
Note the general equation of a circle is x^2 + y^2 = r^2, with centre (0, 0) and radius: r.
So, our equation of a circle is (x + 3)^2 + (y - 1)^2 = 100
Subtract 100 from both sides and plug in the points. If it equals to 0, then the points satisfy the equation of the circle (ie lies on the circle)
Your answer is C.
Hope this helped.
Greater then or less then
3x + 11y = 4
2x + 6y = 0
I got
15/2, -5/4
