Consider u = {x|x is a negative real number}
which is an empty set?
{x\x e u and x has a negative cube root}
{x|x eu and x has a negative square root}
{x|x e u and x is equal to the product of a positive number and -1}
{xx eu and x is equal to the sum of one negative and one positive number}

1 and 2

what?

step-by-step explanation:

what do you need with. i love quadrants. can you tell me ?

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
