If x squared y squared equals 25 xy equals 5 prove that x over y plus y over x equals 5 somebody HELP?
x/y = 5/(y^2) and y/x = 5/(x^2). So x/y + y/x = 5/(y^2) + 5/(x^2), which equals 5x^2/(x^2 y^2) + 5y^2/(x^2 y^2) equals 5(x^2 + y^2)/25 equals (x^2 + y^2)/5. x^2 = 25/y^2, so you get (25/y^2 + y^4/y^2)/5 equals ((25 + y^4)/y^2)/25, which shows that your math teacher is on crack. Seriously, I'm not sure that's true.
If y equals one-forth x and x equals -12 then what is y?
x equals -12 and y equals 1/4 of -12, so y = -3.
If y equals 3x and 3x equals 12 then what does y equals?
Well, if 3x equals 12, then x equals 4. And if y equals 3x, then y equals 3 times 4, which is 12. So, y equals 12. Math can be a piece of cake when you break it down like that!
A math problem that equals 1 with 3 variables?
4(x)=12 2+x-y=3 x+y+z=15 4(x)-z+y=1 And in case you didn't figure it out, x is 3, y is 2 and z is 10
If y varies inversely as x and y equals 3 when x equals 6 find the value of x when y equals 18?
3
Geometry math y equals 3x-5 andy equals 6x-2?
x = -1 and y = -8
What is the answer to x plus y equals 3 and 2x-y equals 3?
Oh, dude, we got a math problem here. So, if you solve those two equations simultaneously, you'll find that x equals 2 and y equals 1. But hey, who needs math when you've got Google, right?

What is the answer for y equals x?
x equals y
What is x equals 4y in slope intercept form?
Oh, dude, you're hitting me with the math questions now? Okay, okay, let me break it down for you. So, "x equals 4y" can be rearranged into slope-intercept form, which is y = mx + b. In this case, you can rewrite "x equals 4y" as y = 1/4x. Boom, there you have it, like, math magic or something.
What algebraic property is 8 equals x and x equals y?
Transitive property: If 8 equals x and x equals y, then 8 equals y.
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).
How do you do this math problem y equals x plus 4 and 3y plus x equals 8?
y = x + 43y + x = 8substituting: 3*(x + 4) + x = 8 => 3x + 12 + x = 8 => 4x = -4 => x = -1and then y = x + 4 = -1 + 4 = 3.So the solution is (x, y) = (-1, 3)
What is y equals x plus 2 when x equals -1 and y equals 5?
If [ y = x + 2 ], then x is not -1 when y = 5.If [ y = x + 2 ],then when x = -1, y = 1,and when y = 5, x = 3.
How do you write in math symbols x equals any number?
x = Y Im not sure if thats right though :P
If y equals one-forth x and x equals -12 then what is y?
x equals -12 and y equals 1/4 of -12, so y = -3.
What the results of x plus 2y-2x-y equals x equals?
The result of the equation x + 2y - 2x - y equals x simplifies to y - x.
