x - 2y=0 so x = 2y
9y - 4x=1
Substituting for x, 9y-4*(2y) = 1 or 9y-8y = 1 so that y = 1
then x = 2y = 2*1 = 2

What is 4x squared y plus 3x squared y?
4 (apples) plus 3 (apples) = 7 (apples). 4 (cows) + 3 (cows) = 7 (cows) 4 (x2y) + 3 (x2y) = 7 (x2y)
Factor x2y - xyb - abx plus ab2?
4
What is the coefficient of the x2y term in the expansion of (x plus 2y)3?
The coefficient is 6.
What is the point of intersection of y equals 2x-x2 and y equals 0?
y = 2x - x2y = 0Since both quantities on the right side are equal to 'y', they're equal to each other.2x - x2 = 0x (2 - x) = 0x = 0and2 - x = 0x = 2The two points of intersection are (0, 0) and (2, 0) .
What is like terms in polynomial?
They are terms in which a variable is raised to the same power (index) in both terms. So x2y and -27x2y are like terms but not xy2.
Solve the equation y' plus x2y equals x2?
(2x)ysquared
Find dyoverdx by implicit differentiation xy2 minus x2y equals 3xy?
Whooop!
What is -2y plus x2y-8?
It is -2y + x2y - 8, which is an expression that cannot be simplified further, not can it be evaluated.
If I know that x2y plus 4 and I plug that into 3y plus 5x what do I get?
You will get nonsense. You cannot plug x2y + 4 into anything!
What is 4x squared y plus 3x squared y?
4 (apples) plus 3 (apples) = 7 (apples). 4 (cows) + 3 (cows) = 7 (cows) 4 (x2y) + 3 (x2y) = 7 (x2y)
A number y varies inversely as the square of x If y equals 2 when x equals 6 what is y when x equals 3?
x2y = k (constant) so 36 x 2 ie 72 is the constant. If x = 3 then y = 72/9 = 8
What is the greatest common factor of x2y xy2?
xy
What is the greatest common factor of x2y and xy2?
xy
What is the GCF of x2y and xy2?
The GCF is xy
Factor x2y - xyb - abx plus ab2?

What is 4xy plus x3y plus yx2 plus yx plus 3yx simplified?
4xy + x3y + yx2 + yx + 3yx = x3y + x2y + 8xy = (xy)(x2y + x + 8)
What is the coefficient of the x2y term in the expansion of x 2y 3?
