There is a nonlinear relationship between x and y when x is less than 0 and a linear relationship when x is greater than 0.
O There is a linear relationship between x and y when x is less than 1 and a nonlinear relationship when x is greater than 1.
There is a linear relationship between x and y when x is less than 0 and a nonlinear relationship when x is greater than 0.
There is a nonlinear relationship between x and y when x is less than 1 and a linear relationship when x is greater than 1

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

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.
