X = 0.5 x 8 = 4
The general equation of a given circle is
Given a plot of the circle in the X-Y plane, The center of circle has the coordinates ( -1, -1) and the circle is passing through (-1 ,-4) and (-1 ,-2) and (-1 ,-4) , (-1 ,-2) are coordinates of diametrically opposite ends of circle
If there are two points on a circle (x₁, y₁) and (x₂, y₂) that are at opposite ends of the same diameter, then the circle's equation can be written as
(x-x₁)(x-x₂)+(y-y₁)(y-y₂)=0
Given x₁= -1 , x₂ = -1 , y₁= -4 , y₂= -2
The circle's equation can be written as ( x+1)(x+1) + (y+4)(y+2)
⇒
⇒
Therefore, is the general equation of circle.
Hence,The general equation of a given circle is

If all your solutions are
<span>A; f(x) = x + 5
B;f(x) = x + 1
C;f(x) = 2x + 1
D;f(x) = –2x – 1
None of the above will work with the data set you have presented. </span>
Answer:
no
Step-by-step explanation:
To determine if (1, 6) is a solution, substitute x = 1, y = 6 into the left side of both equations and if the value obtained equals the right side then it is a solution.
10(1) - 6 = 10 - 6 = 4 ≠ - 6
- 10(1) + 5(6) = - 10 + 30 = 20 ≠ 30
Then (1, 6 ) is not a solution to the system
