What is one difference between a variable expression and a numerical expression?
The variable.
What is an expression containing at least one variable called?
Variable expression.
Is 2x plus 5y plus 2 a polynomial?
Yes, since the expression contains more than one variable, then 2x+5y+2 is a polynomial.
Can a experiment have more than one independent variable?
yes it can I've done a few experiments that have had more than one independant variable.
Is a variable a monomial?
A monomial is an expression that is either:1) a numeral,2) a variable,or 3) the product of a numeral and one or more variables.A variable can be thought of as the product of the numeral 1 and the variable, thus making it a monomial.
Is an expression that contains at least one variable?
yes it should contain one variable or more.
Can you have more than one variable?
Yes, you can have more than one variable
What is one difference between a variable expression and a numerical expression?
The variable.
What is an expression containing at least one variable called?
Variable expression.
What is an expression that contains at least one variable.?
An algebraic expression is a type of expression that contains a variable or variables.
What is an expression that contains a variable a number and at least one operation?
That looks like the description of an EXPRESSION. However, an expression need not have "at least one operation"; a single number, or variable, is a perfectly valid expression.
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
A mathematical phrase that includes one or more variables?
A variable expression.
What is one difference between a variable and a numerical expression?
The variable.
Is 2x plus 5y plus 2 a polynomial?
Yes, since the expression contains more than one variable, then 2x+5y+2 is a polynomial.
Does a variable expression consists only of numbers?
An algebraic expression can have a mixture of numbers and variables, but it does not contain an equals sign.
Can a experiment have more than one independent variable?
yes it can I've done a few experiments that have had more than one independant variable.
