What is the Sum of three x minus y equals twelve?
What is 3x-6y=12
If x equals two thirds and y equals five sixths what is the fraction of one over x and one over y?
5/4
What is y equals x over 11?
It is a linear relationship between x and y.
Does slope equals change in y change in x?
yes, change in y over change in x equals slope
What is x in terms of y and z when 1 over y equals 1 over x plus 1 over z?
x = yz/(y - z)
If y varies directly as x and y equals fifteend and when x equals three find y when x equals twelve?
y is directly proportional to x. When y = 15, x = 3 therefore y = 5x When x = 12, then y = 5 x 12 = 60.
What does n over x plus n over y equal?
It equals n(x+y) / x*y.
What is the Sum of three x minus y equals twelve?
What is 3x-6y=12
If x equals two thirds and y equals five sixths what is the fraction of one over x and one over y?
5/4
What is y equals x over 11?
It is a linear relationship between x and y.
T over y equals x over w solve for x?
T/y = x/wMultiply each side by 'x':Tw/y = x
Does slope equals change in y change in x?
yes, change in y over change in x equals slope
What is x in terms of y and z when 1 over y equals 1 over x plus 1 over z?
x = yz/(y - z)
What is the answer to x over 4 minus y over three equals one?
x=4, y=3
If y equals 1 over 3 x and x equals -18 find y?
If y(x) = 1/3x, y(-18) = 1/[3(-18)] = -1/54.
What kind of lines are y equals 2X plus 4 and X plus 2Y equals twelve?
The lines are mutually perpendicular.
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.
