The center of a circle is 5 units below the origin, and the radius is 10 units. what is the equation of the circle? x^2+(y+5)=10

(x+5)^2+y^2=10

x^2 + (y+5)^2=100

(x+5)^2+y^2=100

(c)

Step-by-step explanation:

Given

the radius of circle=10 units

The center is 5 units below the origin i.e. (0,-5) is the center

The general equation of a circle is

Putting values

Second last option is correct

step-by-step explanation:

you divide the denominator by the numerator on both sides and if the quotients are equal then the fractions are equivalent

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
