If xy equals x or yx equals x what is y?
xy = x ÷x y = 1
What are the coordinates of the points of intersection of x-2y equals 8 and xy equals 24?
Using: x - 2y = 8 y = (x - 8)/2 Substituting in: xy = 24 => x(x - 8)/2 = 24 => x2 - 8x = 48 => x2 - 8x - 48 = 0 => (x - 12)(x + 4) = 0 => x = 12 or -4 => y = 2 or -6 respectively (since xy = 24) ie the points (12, 2) and (-4, -6)
How Product of x and y decreased by 8?
x and y are variables, so unless you define their values, this question has no definite answer. but, i can simplify it for you: xy-8, x*y-8, (xy)-8, xy+-8. There are a lot more ways, but i recommend you use XY-8.
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.
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
X plus XY equals 8 solve for Y?
x+xy=8 xy=-x+8 y=-1+8/x
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.
If x equals -8 and xy equals 1 then what does y equal?
-1/8 -8*-1/8 = 1
How do you solve xy equals 3?
If you're solving for x, then x = 3/y.
If xy equals x or yx equals x what is y?
xy = x ÷x y = 1
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 adds up to 11 and multiplies to 24?
x + y = 11 xy = 24 y = 11-x xy = x (11-x) = 24 11x - x^2 = 24 x^2-11x + 24 = 0 (x-8)(x-3) = 0 x = 8 or 3 xy = 24; y =3 or 8 Answer 8 and 3
What are the coordinated when x-2y equals 8 intersects with xy equals 24?
The coordinates are: (-4, -6) and (12, 2)
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 are the coordinates of the points of intersection of x-2y equals 8 and xy equals 24?
Using: x - 2y = 8 y = (x - 8)/2 Substituting in: xy = 24 => x(x - 8)/2 = 24 => x2 - 8x = 48 => x2 - 8x - 48 = 0 => (x - 12)(x + 4) = 0 => x = 12 or -4 => y = 2 or -6 respectively (since xy = 24) ie the points (12, 2) and (-4, -6)
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.
What gives you -11 when add and 24 when multiplied?
