(2y-4)/(y+3)=(2-y-2)/(y+3) --> multiply both sides by (y+3)
2y-4=2-y-2 --> 2-2=0 (right hand side)
2y-4=-y --> add y to both sides
3y-4=0 --> add 4 to both sides
3y=4 --> divide both sides by 3
y=4/3

Find the radius of a circle with the equation x2 plus y2 equals 16?
x2 +y2 = R2 =16 = radius 2 R = 4
Find the center and radius of the circle with this equation x2 plus y2 plus x equals 0?
x2+y2+4x+2y+3=0(x+2)2 + (Y+2.5)2 = 3This is the equation of circle with center at (-2,-2.5) with radius 3.5
How do you find the radius of the circle with the given equation of x2 plus y2-10x plus 4y plus 4 equals 0?
Given: x2 + y2 - 10x + 4y + 4 = 0 First, we'll move our constants to the right: x2 + y2 - 10x + 4y = -4 Then group terms with the same variables together: x2 - 10x + y2 + 4y = -4 Then complete the squares: x2 - 10x + 25 + y2 + 4y + 4 = -4 + 25 + 4 (x - 5)2 + (y + 2)2 = 25 And there we have it. This is an equation for a circle whose center point is at (5, -2), with a radius of √25, which equals 5.
What is the diameter of the following circle x2 plus y2 equals 144?
x2 + y2 = 144 = radius squared radius = sqrt (144) = 12 diameter = 2 x radius = 24
What is the value of 3x2 - y2 if x equals -1 and y equals 3?
x = -1y = 33x2 - y2 = 3 (-1)2 - (3)2 = 3 (1) - 9 = -6
Which choice shows y2 in isolated form x plus 4 2 plus y2 equals 22?
y^2=-x^2-8x+6
How do you solve the equation. X2 plus y2 plus z2 - 4x plus 4y plus 2z plus 5 equals 0 x2 plus y2 plus z2 equals 4?
(2-r)e-rr
If a plus b plus c equals x plus y plus z then prove a2 plus b2 plus c2 equals x2 plus y2 plus z2?
a2+b2+c2=x2+y2+z2 divide each side by 2 (a2+b2+c2)/2=(x2+y2+z2)/2 a+b+c=x+y+z
What is the answer to x squared plus y squared equals 25?
X2+y2=25 (x-8)2+y2 =41
What is the radius of x2 plus y2 equals 9?
X2 or 2 times x?
X2 plus y2 equals 13 where y equals 2?
If y=2 then that means x^2=9 and x= 3 or -3
If xy equals x2 plus y2 plus 2xy?
If:xy = x2 + y2 + 2xyThen:x2 + xy + y2 = 0Do you want to solve it for x?x2 + xy + (y/2)2 = (y/2)2 - y2(x + y/2)2 = y2/4 - y2x + y/2 = ± √(-3y2/4)x = -y/2 ± y√(-3) / 2x = (-y ± yi√3) / 2
Find the radius of a circle with the equation x2 plus y2 equals 16?
x2 +y2 = R2 =16 = radius 2 R = 4
How do you derivative x plus y - 1 equals ln x2 plus y2?
There are several steps involved in how one can solve the derivative x plus y - 1 equals x2 plus y2. The final answer to this math problem is y'(x) = (1-2 x)/(2 y-1).
X2 plus y2 equals 30 what is the circumference of the circle?
(2 pi) x sqrt(30)
X2 plus y2 equals 4?
The graph of that equation is a circle, centered at the origin, with radius = 2 .
