Given:
The equation of a circle is:
To find:
The center and radius of the circle.
Solution:
We have,
To make complete square add square of half of x and square of half of y on both sides.
...(i)
The standard form of a circle is:
...(ii)
On comparing both sides, we get
Therefore, the center of the circle is (-2,3) and the radius is 3 units.
the value of the lower quartile is 2 because that’s where the box ends
X - 1 is not null => x is not 1 => D = R - {1};
The answer is a. the first step is to divide the whole bottom equation by -1 because x can’t be negative. you then plug in y + 9 into the first equation to solve. so the equation would be (y + 9) + y = 11. you do this because in substitution you plug in one of the equations into the other equation. you then get 2y + 9= 11. you would next subtract 9 to both sides which leaves you with 2y= 2, divide by both sides, y = 1. you then plug the why value into the first equation to figure out the value for x. so it would be x + 1 = 11, subtract 1, x equals 10.
sorry this was hard to explain! hope this helps!
