y^3

Ah, what a lovely question. When you multiply "y" by itself three times, you're actually raising "y" to the power of 3, which can be written as y^3. It's like painting a beautiful little tree with three layers of leaves, each one adding to the beauty of the whole picture.
Oh, dude, you're hitting me with some math now? Like, okay, so if you mean y multiplied by itself three times, it's y^3. So, like, it's y cubed. But, like, who really needs to know that, right?
In mathematics, when you see an expression like y x y x y, it means multiplying y by itself three times. This can also be written as y^3, which represents y cubed. So, y x y x y is equal to y^3.
(y * x) - y = y * (x - 1)
you subtract x from both sides for both equations to get it in y= form. so... x+y=5 x+y-x=5-x y=5-x x+y=6 x+y-x=6-x y=6-x thanks:D but i meant with absolute value signs it was supposed to look like this : |x+y|=5 and |x|+|y|=6 ... but when i typed it in answers.com changed it
Twice the sum of 'x' and 'y' . . . 2(x+y) The sum of twice 'x' and 'y' . . . (2x+y)
given: x - 4 = -y or, -y = x - 4 or, y = -(x - 4) or y = -x + 4 or y = 4 - x i.e. for x > 4, the equation x - 4 = -y is true.
If y varies directly as x and y is 18 when x is 24, then y is always three fourths of x. So if y is 15, then x is 20.
