User: The equation of a circle whose center is at (1,2) and radius is 5 is (x 1) (y 2) = 5 (x - 1) (y - 2) = 25 (x - 1) - (y - 2) = 25

Weegy: The equation of a circle whose center is at (1, 2) and radius is 5 is (x - 1)? + (y - 2)? = 25



User: The distance between the points (3, 3) and (7, 3) is 4 13 6

Weegy: 13/6= 2.17. In mixed number it is 2 1/6. 13/6 is an irreducible fraction.

User: The center of the circle whose equation is (x + 2)² + (y - 3)² = 25 is (2, -3) (-2, 3) (2, 3)

User: The center of the circle whose equation is (x + 1)² + (y + 2)² = 49 is (1, 2) (-1, -2) (1, -2)

Weegy: The center of the circle whose equation is (x + 1)? + (y + 2)? = 49 is (-1, -2)



User: The equation of the circle whose center is at (2, 1) and radius is 3 is (x + 2)² + (y + 1)² = 9 (x - 2)² + (y - 1)² = 9 (x - 2)² + (y - 1)² = 3

Weegy: The equation of the circle whose center is at (2, 1) and radius is 3 is (x - 2)? + (y - 1)? = 9.



User: The radius of the circle whose equation is (x - 3)² + (y + 1)² = 16 is 4 8 16

Find the center of the following equation. x 2 + y 2 + 8 x - 6 y - 15 = 0
Question
Updated 11/10/2014 11:24:59 PM
1 Answer/Comment
x^2 + y^2 + 8x - 6y - 15 = 0
(x + 4)^2 - 16 + (y - 3)^2 - 9 - 15 = 0
(x + 4)^2 + (y - 3)^2 = 40
(-4 , 3) is the center of equation.:x^2 + y^2 + 8x - 6y - 15 = 0 .

The distance between the points (5, -2) and (-7, 3) is 13 .
Let the distance is d
d^2 = (-7-5)^2 + {3 - (-2)}^2
d^2 = 144 + 25
d^2 = 169
d = 13

The solution set for (x + 2)(2x + 3) = 6 is {-7/2, 0}.

(x + 2)(2x + 3) = 6;
2x^2 +3x + 4x + 6 = 6;
2x^2 + 7x + 6 - 6 = 0;
2x^2 + 7x = 0;
x(2x + 7) = 0;
x = 0;
2x + 7 = 0; 2x = -7; x = -7/2
