If xy equals x or yx equals x what is y?
xy = x ÷x y = 1
X equals 5 y equals 5 what is xy?
You cannot have xy= anything. Only x can be there at the end. x=5y=5 Divide 5y for all 3 sides to get 5xy=y Then divide y from both sides to get 5x=1 Therefore, x=1/5
If xy plus y equals z then x equals?
xy + y = z xy = z - y (xy)/y = (z - y)/y x = (z - y)/y
What is the property for xy equals 1 xy?
That is the commutative property of equality.
If xz plus zy equals xy and xz equals zy then the point z is?
mid point of xy
Xy plus yx equals 545 what is the value of x and y?
xy and yx are identical so you have 2xy = 545 ie xy = 272.5. Possible answers 5 and 54.5, 10.9 and 25 etc
Find the inverse variation equation if x equals 5 when y equals 9?
The equation is xy = 5*9 = 45 Alternatively, y = 45/x
What is the value of the expression 4x-2y plus xy when x equals -1and y equals 5?
Just plug in the values for x and y. 4(-1) - 2(5) + (-1)(5) = -19
Is y equals 5 a function?
Yes, it is.
