x times y
or, symbolically, either x*y or simply xy
(where context allows, also X x Y)
y - 5x
X = 15 - 5y
The expression (4xy) represents a monomial where 4 is the coefficient and (xy) is the product of the variables (x) and (y). It indicates that the value of the expression is obtained by multiplying 4 by the values of (x) and (y). This expression is often used in algebra to represent relationships in equations or to describe quantities in various mathematical contexts.
That depends on the value of x and y. As an expression, "x + y" can't be simplified.
To factor out the expression: x2y-y3 First factor out one "y": y(x2-y2) The expression x2-y2 is a difference of squares, which factors as well: (y)(x-y)(x+y) This is the simplest factoring of the original expression.
y - 5x
2(xy)
yz - x
0.5*xy
4(x+y)
This phrase might be represented by the mathematical expression Y + (-5x). Because there is no additional information, you cannot determine what either Y or x is.
X = 15 - 5y
The expression xy + z represents the sum of the product of x and y with the value of z. This is a simple algebraic expression where x and y are variables representing numbers, and z is a constant value. To find the result of xy + z, you would first multiply x and y, and then add the value of z to the product.
As a term of an expression: x-y
It is x*x + y*y*y*y
The expression (4xy) represents a monomial where 4 is the coefficient and (xy) is the product of the variables (x) and (y). It indicates that the value of the expression is obtained by multiplying 4 by the values of (x) and (y). This expression is often used in algebra to represent relationships in equations or to describe quantities in various mathematical contexts.
The sum of x and y decreased by their product is (x + y)- xy.
