What is its center

Respuesta :

Answer:

Center is [tex](-12,9)[/tex]

Step-by-step explanation:

Given: Equation of a circle is [tex](x+12)^2+(y-9)^2=35[/tex]

To find: center of the circle

Solution:

A circle is a locus of all points which are at equidistant from the fixed point (center).

Equation of a circle is of form [tex](x-a)^2+(y-b)^2=r^2[/tex] where [tex](a,b)[/tex] represents center of the circle and r denotes radius of the circle.

Given equation is [tex](x+12)^2+(y-9)^2=35[/tex]

[tex]\left [ x-(-12) \right ]^2+(y-9)^2=35[/tex]

Compare this equation with [tex](x-a)^2+(y-b)^2=r^2[/tex]

Center is [tex](a,b)=(-12,9)[/tex]
