Complete the squares to get

x^2+y^2=2x-6y+6

\implies(x^2-2x+1)+(y^2+6y+9)=16

\implies(x-1)^2+(y+3)^2=4^2

which is the equation of a circle centered at (1, -3) with radius 4, and thus with area 16π.

Answer:

Step-by-step explanation:

First, add 3 to both sides:

-5 = -6∛(x²)

Next, divide both sides by -6, to isolate ∛(x²):

5/6 = ∛(x²)

Eliminate the radical by cubing both sides:

5³

---- = x²

6³

Finally, take the square root of both sides.  This will isolate x.  There will be two roots:  one +, the other -.

x = ±√(5³/6³)

This simplifies to:  ± (5/6)∛(5/6).

Which expression is not a polynomial?<br> 11p-7q<br> 8xy^4-5x^3y<br> 2-x<br> -4/y
kkurt [141]
A polynomial is an expression that has two or more than terms. These terms are separated by an operation. Only -4/y is not a polynomial. It is a monomial. Monomial is not a polynomial.

Find the difference using fraction bars or a paper and pencil. Write your answer in simplest form.
nasty-shy [4]
First, find the lowest common denominator. That is 12. You only have to change 3/4 into 12ths.

3/4 = 9/12

11/12 – 9/12 = 2/12 = 1/6
