Sea P(x, y) un punto que está en la gráfica de la función y = x2 - 8. a) Exprese la distancia "d" que hay desde P hasta el origen expresado como función de "x". b) ¿Cuánto vale "d" si x = 0? c) ¿Cuánto vale "d" si x = - 1?

answer: i can’t tell you that

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.

multiplication is multiplication.   it might feel harder depending on what level of math you are in, but generally it will be the same old stuff, while implementing some new concepts and methods of solving work.
