Álvaro le regaló a su primo Jorge un ordenador que costó 1347 euros y un móvil que le costó 866 euros menos que el ordenador. Si tenía 2000 euros para pagar, ¿cuánto dinero le sobra? Si el euro equivale a $3750 colombianos. ¿Cuántos pesos colombianos le quedaron a Álvaro?

step-by-step explanation:

0

1 + (6 / x - 1)

step-by-step explanation:

divide using polynomial division.

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.
