Suppose y varies inversely with X use the information to find K and choose the equation of variation. X equals 7 and y equals 3?
xy = K so K = 21
Complete the equation of variation where y varies inversely as x and y equals 4 when x equals 2?
xy = 8 or y = 8/x
What is the equation of an inverse relationship?
The equation is xy = k where k is the constant of variation. It can also be expressed y = k over x where k is the constant of variation.
If Y varies directly as x and y equals seventy-five when x equals five find y when x equals one?
y = x/k so k = 1/25; when x = 1, x/k, hence y, = 25
What is xy plus z equals 9 for y?
xy + z = 9Subtract 'z' from each side:xy = 9 - zDivide each side by 'x':y = (9 - z) / x
If X varies inversely as Y and X equals -24 when Y equals 15 find X when Y equals -36?
xy = is a constant (k) so k = -360. When y = - 36, x = 10
If xy equals x or yx equals x what is y?
xy = x ÷x y = 1
Suppose y varies inversely with X use the information to find K and choose the equation of variation. X equals 7 and y equals 3?
xy = K so K = 21
Solve xy-8 equals k for y?
Think of it like this: you need to rearrange things so y is by itself on one side of the equation: xy-8=k First add 8 to both sides to get rid of the 8 on the y side: xy-8+8=k+8 xy=k+8 Divide both sides by x to get y by itself: (xy)/x=(k+8)/x y=(k+8)/x That's it. Just remember that you always add or subtract before multiplying or dividing.
If xy plus y equals z then x equals?
xy + y = z xy = z - y (xy)/y = (z - y)/y x = (z - y)/y
X plus XY equals 8 solve for Y?
x+xy=8 xy=-x+8 y=-1+8/x
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.
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.
What is xy-2 when x equals 5 and y equals 4?
18
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.
What does an inverse variation equation look like?
y = k/x of xy = k where k is a constant.
What does X times Y equal with no variables?
It equals XY.
