x times y
or, symbolically, either x*y or simply xy
(where context allows, also X x Y)
y - 5x
X = 15 - 5y
The verbal phrase "the sum of x and y" can be translated into the algebraic expression ( x + y ). This expression represents the addition of the variables ( x ) and ( y ).
An algebraic expression that is a product with a factor of 5 can be represented as ( 5x ), where ( x ) is any variable or expression. This indicates that 5 is multiplied by ( x ). Other examples could include ( 5(y + 2) ) or ( 5a^2b ), where the factor of 5 is present in the product.
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.
y - 5x
2(xy)
yz - x
0.5*xy
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.
4(x+y)
The expression (y - 2)(x^3) is already factored, where the factors are (y - 2) and (x^3). The factor (y - 2) indicates that y can take on any value except 2, while (x^3) signifies that the value of x can be any real number since it is raised to the third power. Therefore, the expression represents a product of these two factors.
X = 15 - 5y
The verbal phrase "the sum of x and y" can be translated into the algebraic expression ( x + y ). This expression represents the addition of the variables ( x ) and ( y ).
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.
An algebraic expression that is a product with a factor of 5 can be represented as ( 5x ), where ( x ) is any variable or expression. This indicates that 5 is multiplied by ( x ). Other examples could include ( 5(y + 2) ) or ( 5a^2b ), where the factor of 5 is present in the product.
As a term of an expression: x-y
