What does it mean to evaluate an expression?
To evaluate an expression is nothing but to operate the given expression according to the operators given in the expression if it is evaluable i.e, it could be convertable.
Evaluate the variable expression for x equals 3?
Take 3 and substitute into the expression given to you but not mentioned in the question here and evaluate the expression. "Sub and Solve" I say.
Evaluate each expression for the given value of the variable 4m-6.5m2?
4x2-6.5 = 2.5
What is this equal 5x 2y 19 x - 2y -1?
That depends on the plus or minus values of some of the terms in the expression that have not been given.
How do you find a point of a linear function?
Given a linear function in n variables, you need to select values for (n-1) of the variables. Solve the resulting function for the nth variable. Then the ordered n-tuple represents the coordinates, in n-dimensional space, of a point that is on the linear function.Selecting different sets of (n-1) variables, and different values will result in different solutions. Together, these will from a line in n-dimensional space.
How can you evaluate a expression?
replace the variables with the given values and simplify using the order of operations.

What does it mean to find the value of an algebraic expression?
When a given set of values for the variables are substituted in the expression the result is the value of the expression.
How do you do evaluate expression?
You have to substitute a value for the letter variable in the expression. This is what we call evaluating the algebraic expression. An example would be 3x+1=7, when x=2.
How would you evaluate the expression 3x-4y equals 9 when x equals 2 and y equals 5?
explain how to evaluate an algebraic expression for given variables. how would we evaluate the expression "3x-4y+9" when x=2and y=5?
What is the expression of 9x plus 4y-5 what is the sum?
The sum of the given expression would depend on the values of the variables which have not been given.
What do you need to be given to evaluate an algebraic expression?
A variable
Evaluate the variable expression for x equals 3?
Take 3 and substitute into the expression given to you but not mentioned in the question here and evaluate the expression. "Sub and Solve" I say.
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.
How are the independent and dependent variables related?
Independent variables can take values within a given boundary. The dependent variable will take values based on the independent variable and a given relationship at which the former can take its values.
How are dependent variables and independent variable the related?
Independent variables can take values within a given boundary. The dependent variable will take values based on the independent variable and a given relationship at which the former can take its values.
What is mathematical or numerical expression?
It is a combination of numbers and variables, linked together by mathematical functions. For example sqrt(2y/3*7.34*pi) where y is some variable. Given the value(s) of the variable(s) it is possible to evaluate (find the value of) the expression.
