What else can I help you with?
Two algebraic expressions are if they have the same value for all values of their variable?
They are identical or equivalent.
What is the difference between a numerical and an algebraic expressions?
A numerical expression uses numbers and operations. It also has an equal sign. An algebraic expression uses variables and operations. Unlike a numerical expression it does not have an equal sign.
What makes up a math equation?
Usually two algebraic expressions that are equal in values
What does evaluating expressions mean?
Calculating the value of the expression when you have substituted numerical values for the variables.
What describes a variable?
A variable is a measurement that can take different "values". I put values in quotation marks because a variable can take qualitative values (for example, colour of eye) as well as quantitative (numerical) ones.
How can you have different values in algebraic expressions?
When the value of a variable in an algebraic expression changes, the value of the expression can change.
Two algebraic expressions are if they have the same value for all values of their variable?
They are identical or equivalent.
An expression that contains at least one variable is called a?
An expression that contains at least one variable is called an algebraic expression. Algebraic expressions consist of variables, constants, and mathematical operations such as addition, subtraction, multiplication, and division. These expressions can be simplified or evaluated by substituting specific values for the variables. Algebraic expressions are fundamental in algebra and are used to represent mathematical relationships and solve equations.
What is the difference between a numerical and an algebraic expressions?
A numerical expression uses numbers and operations. It also has an equal sign. An algebraic expression uses variables and operations. Unlike a numerical expression it does not have an equal sign.
What is the definition of equivalen variable expressions?
Two expressions are "equivalent" if they have the same result for any values of the variable or variables.
How do you find the value of an algebraic expression by substituting a number for each variable and simplifying?
The answer to the question is given in the question!If you want to find the value of an algebraic expression, then you need to substitute numerical values for each of the variables in the expression, and then calculate and simplify the result.
What makes up a math equation?
Usually two algebraic expressions that are equal in values
What does evaluating expressions mean?
Calculating the value of the expression when you have substituted numerical values for the variables.
How do you evaluate algebraic expressions?
Replace the variables with the correct values and calculate using the order of operations
What describes a variable?
A variable is a measurement that can take different "values". I put values in quotation marks because a variable can take qualitative values (for example, colour of eye) as well as quantitative (numerical) ones.
What advantage is there to using algebraic equations instead of numerical values when defining the dimensions of a CAD model?
There is none.
What type of variable is household income?
Household income is a quantitative variable, specifically a continuous variable, since it can take on a wide range of numerical values.
