Nancy has to find the reflection of a point across the x-axis. How can she find the new coordinates without graphing the point? Is there a rule that she can apply to find it?

the only thing she needs to know is that in a reflection across the x-axis is when the x coordinate stays the same and the y-coordinates change.

Step-by-step explanation:

what does muffins have to do with anything?

step-by-step explanation:

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.
