xy = x ÷x y = 1
"xy" refers to the product of "x" and "y". Just substitute the variables for numbers, and do the multiplication.

The GCF is xy
It is XY^2 or X*Y*Y
xy = x ÷x y = 1
xy + y = z xy = z - y (xy)/y = (z - y)/y x = (z - y)/y

x+xy=8 xy=-x+8 y=-1+8/x
The equation is xy = 5*9 = 45 Alternatively, y = 45/x
k = x y x = k/y
So far you know that: x=-8 xy=1 so xy means x times y. If you split xy. y=1/x or y=1/-8 1/-8= -0.125 You can find out that this is correct with the formula xy=1 because -0.125 x -8 is 1.
If Y = 0 then there is no value of X such that XY = 1.
"xy" refers to the product of "x" and "y". Just substitute the variables for numbers, and do the multiplication.
Inverse proportion implies xy = c where c is the constant of [inverse] proportionality. x = 2 and y = 36 implies xy = 72 = c So the relationship is xy = 72 Then, if x = 4, y = 72/x = 72/4 = 18
To find the value of the expression 4x - 2y + xy when x = -1 and y = 5, we first substitute the values of x and y into the expression. This gives us 4(-1) - 2(5) + (-1)(5). Simplifying this further, we get -4 - 10 - 5, which equals -19. Therefore, the value of the expression is -19 when x = -1 and y = 5.
So 5 = (xy)^2 and x = 2.5. This means that 5 = (2.5y)^2. So sqrt(5)/2.5 = y when x = 2.5. Now if x = 9 then 5 = (9y)^2. So sqrt(5)/9 = y. This means that for any x in this relation y = sqrt(5)/x.
