5x + y = 5.....multiply by -2
10x + 3y = 20
------------------
-10x - 2y = -10 (result of multiplying by -2)
10x + 3y = 20
-----------------add
y = 10

5x + y = 5
5x + 10 = 5
5x = 5 - 10
5x = -5
x = -5/5
x = -1

solution is (-1,10)

A circle that has a center at the point (3, -2) with a radius of 6. Write an equation for the circle.
crimeas [40]

Answer:

(x – 3)^2+ (y +2)^2 = 36

Step-by-step explanation:

Given data

The formula for the equation of a circle is (x – h)2+ (y – k)2 = r^2,

where (h, k) represents the coordinates of the center of the circle

h=3

k=-2

r= 6

Substitute

(x – 3)^2+ (y – (-2))^2 = 6^2

(x – 3)^2+ (y +2)^2 = 36

Hence the expression for the equation of the circle is

(x – 3)^2+ (y +2)^2 = 36
