x2 + y2 - 10x + 4y - 52 = 0
x2 - 10x + y2 + 4y = 52 Complete the square
(x2 - 10x + 25) + (y2 + 4y + 4) = 52 + 25 + 4
(x - 5)2 + (y + 2)2 = 81
(x - 5)2 + (y - -2)2 = 92
This is the equation of a circle with center (5, -2), and radius 9.

What are the solutions to the simultaneous equations of 3x -y equals 5 and 2x2 plus y2 equals 129?
The solutions work out as: x = 52/11, y = 101/11 and x = -2, y = -11
How do you factorise y squared plus 9y minus 52?
y^2+9y-52 = (y+13)(y-4)
What are points of intersection of the line 3x -y equals 5 with the curve of 2x squared plus y squared equals 129?
Straight line: 3x-y = 5 Curved parabola: 2x^2 +y^2 = 129 Points of intersection works out as: (52/11, 101/11) and (-2, -11)
What equals 152?
There are an infinite number of possible answers. 152*1 or 151+1 or 153-1 or 153/1 and then we can try with 2, 3, 4, etc and then with 0.1, 0.2 etc and then 1.1, 1.2, 1.3, ... 2.1, 2.2, 2.3, ... 3.1, etc and then irrational numbers.
What is the largest integer value of x given that -52x is less than or equal to 7?
-52x <= 7 (-52x)/(-52) >= 7/(-52) {divide both sides by -52, and reverse the inequality when dividing by a negative. x >= -7/52 There is no largest integer value for x. If the question was ... greater than or equal to ... then the solution would be x <= -7/52, and the largest integer value would be -1.
What is the radius of x2 plus y2 - 10x plus 4y - 52 equals 0?
Complete the squares: x2 - 10x + 25 + y2 + 4y + 4 - 52 = 25 + 4 = 29 x2 - 10x + 25 + y2 + 4y + 4 = 52 + 29 = 81 So the radius is sqrt(81) = 9
What does 95 plus 52 plus 95 plus 52 equals?
95 plus 52 plus 95 plus 52 equals 294.
What is 8x6 plus 4 equals?
8x6 plus 4 equals 52.
What are the points of intersection when the line y equals 10x -12 crosses the curve y equals x squared plus 20x plus 12?
If: y = 10x -12 and y = x^2 +20x +12 Then: x^2 +20x +12 = 10x -12 Transposing terms: x^2 +10x +24 = 0 Factorizing: (x+6)(x+4) = 0 => x = -6 or x = -4 Points of intersection by substitution are at: (-6, -72) and (-4, -52)
68-3x equals 10x plus 16?
68-3x=10x+16 Combine like terms. (Subtract 16 from both sides. Subtract -3x from both sides.) This will give you: 52=13x Divide both sides by 13. Your answer is x=4.
