What is the variable in 3x2y in algebra?
They are: x and y and the expression can be simplified to 6xy
Does y plus 15 equal a variable or variables?
'y' is a variable. '15' is not. [ y+15 ] is an expression in one variable.
Is y² a variable or just y?

What is the variable of this algebraic expression 5 plus y plus 8?
In the expression 5 + y + 8, y is a variable. We know how much 5 and 8 are, those are definite quantities. Only y has an unknown, and hence variable value.
What is y-5 -5?

What is the variable in expression 2y 7?
y
What is the variable in the expression 4y plus 9?
4y + 9The variable is Y. The variable is the letter (the unknown amount)
What is the variable of this algebraic expression 5 plus y plus 8?
In the expression 5 + y + 8, y is a variable. We know how much 5 and 8 are, those are definite quantities. Only y has an unknown, and hence variable value.
What is a indendent variable?
You may be referring to an independent variable, which is a quantity in a mathematical expression whose value does not depend upon variations in other quantities in that mathematical expression. For example, in the expression y=2x the variable y depends on the value of x and so is not independent, while in the expression z=x+y the variable z is dependent, but the variables x and y are both independent.
Which is the variable expression for Seventeen decreased by a number y?
17 - y

What do you call replacing a variable in an expression by a number?
A variable is a letter that represents a number. An expression that contains at least one variable is called variable expression, also called algebraic expression. A variable expression has one or more terms. A term is a number, a variable, or a product of numbers and variables. For example,3(x^2)y + 2xy + x - 7 is a variable expression, where you have 4 terms.When working with variable expression, you often use the substitution principle:If a = b, then a may be replaced by b in any expression.The set of numbers that a variable may be represent is called replacement set, or domain, of the variable. To evaluate a variable expression, you replace each variable with one of its values and simplify the numerical expression that results.Example: Evaluate the expression 2x - 4y for x = 5 and y = -9.Solution:2x - 4y= 2(5) - 4(-9)= 10 + 36=46
What is a variable expression for the product numbers y and 2?
It is 2y.
