How do you solve mathematical equations using the subsitution method?
Say you have a pair of equations like a+b=1 and 2a+3b=5. To solve using substitution you would set one equation against one variable (say a=1-b) then plug that into the other (2(1-b)+3b=5), then solve for the one variable you have there and then plug that result into the other equation (in this case b=3 and a=-2).
What is the variable called that changes in response to another variable?
The answer is a dependent variable. A variable that changes in response to another variable is called a dependent variable.
What variable is influenced by the variable that is manipulated?
The dependent variable.
What are some facts about independent and dependent variable?
An independent variable is a variable which, in the context of the experiment or the observations, can affect the dependent variable but is not affected by it. By contrast, the dependent variable is affected by changes in the independent variable. It is quite possible that there is no independent variable, as such, and each variable affects the other.
What does a variable stand for in math?
A variable is a very important thing when you are doing an experiment. These are things that have an effect on the experiment. There are three categories of variables in math:The controlled variable: variable the never changesThe manipulated variable: variable that does changeThe responding variable: the result of the experiment
How do I plug in a variable?
You cannot plug in a variable, what you do is plug in the value for a variable. If you know the value of the variable in an equation (or formula), the process of replacing that variable whenever it appears in the equation by its value is called plugging in the value for the variable.
How do you use substitution to solve equations?
You plug in what the variable is equal to for that variable then you will be able to finish the problem

What are the ways to solve a system of linear equations in two variables?
the substitution method in which you take each variable and you find out the value and then plug it into the original equation.the adding and subtracting method in which you subtract\add equations to take out a variable and you can figure out what the other variable is. then you also substitute that into that into the original variable
How do you check your answer when factoring trinomials?
plug some numbers in for your variable and see if the factored answers match the pre-factored answer
What is the difference between no solution and undefined?
undefined means you can not do the operation (5/0 is undefined) no solution refers to an equation not having an answer. a solution is a number which you can plug into the variable of an equation and get a true statement. So having no solution means there is no number which you can plug in and get a true statement. As a fraction is not an equation, but an expression it is not right to say that 5/0 has no solution. There is no variable in 5/0, nothing to plug into to get a true or false statement.
What are the advanced trends in internal combustion engines?
Variable cam timing , direct fuel injection , coil over plug ignition,
What is an equation relating period and length for each of the graph?
Formula: Periodxlength The only numbers you plug in are period and length. X remains a variable.
How do you solve a linear equality with two unknowns?
Isolate one of the variable using inverse operations. Then solve. Example: 2x + 4y = 0 --subtract 4y>> 2x = -4y --divide by -4>> -1/2x = y --plug in your variable -->>
