If xy equals x or yx equals x what is y?
xy = x ÷x y = 1
If x equals 0 and y equals 1 what is the value of xy?
"xy" refers to the product of "x" and "y". Just substitute the variables for numbers, and do the multiplication.
What is -xy when x equals -8 and y equals 3?
When x equals -8 and y equals 3, the expression -xy becomes -(-8)(3). Multiplying -8 and 3 gives us -24. Therefore, -xy equals -24 in this scenario.
What is the GCF of x squared y and xy squared?
The GCF is xy
Assume that y varies inversely as x. If y equals -6 when x equals-2 find y when x equals 5?
-6/y=5/-2 5y=12 y=12/5
If xy equals x or yx equals x what is y?
xy = x ÷x y = 1
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 xy-2 when x equals 5 and y equals 4?
18
X plus XY equals 8 solve for Y?
x+xy=8 xy=-x+8 y=-1+8/x
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 k equals xy for x?
k = x y x = k/y
If x equals -8 and xy equals 1 what does y equal?
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.
Find the coordinate of X if XY equals 1 and the coordinate of Y is 0?
If Y = 0 then there is no value of X such that XY = 1.
If x equals 0 and y equals 1 what is the value of xy?
"xy" refers to the product of "x" and "y". Just substitute the variables for numbers, and do the multiplication.
In inverse proportion x equals 2 and y equals 36 but what will y be when x equals 4?
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
What is the value of the expression 4x-2y plus xy when x equals -1and y equals 5?
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.
If y varies inversely as the square of x and y equals 5 when x equals 2.5 what is the value of y when x equals 9?
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.
