How do you graph nonlinear equations?
Select a number of different values for the independent variable (usually x). For each x, calculate the value of the dependent variable using the nonlinear equation. Call these f(x). On a Cartesian plane, mark the points whose coordinates are(x,f(x)) and join them by a smooth curve.
What is of system of equations?
It is essentially a list of equations that have common unknown variables in all of them. For example, a+b-c=3 4a+b+c=1 a-2b-7c=-2 would be a system of equations. If there are the same number of equations and variables you can usually, but not always, find the solutions. Since there are 3 equations and 3 variables (a, b, and c) in this example one can usually find the value of those three variables.
The step that usually comes last in solving numeric problems is?
evaluate
When tackling a difficult question which is not usually a problem solving step that you use to help you find the right answer?
Twiddling your thumbs - certainly NOT a problem-solving step.

What is usually the first step in solving a system of equation by substitution?
The first step is to solve one of the equations for one of the variables. This is then substituted into the other equation or equations.
How do you solve an equation with two variables?
By substitution or elimination of one of the variables which usually involves simultaneous or straight line equations.
Which type of solver is usually the default?
nonlinear

What methods of solving systems are needed to solve a three variable system?
Simultaneous equations are usually used in mathematics to find the values of three variables within a system.
Do linear equations contain x squared?
No, linear equations don't have x2. Equation with x and y are usually linear equations. Equations with either x2 or y2 (but never both) are usually quadratic equations.
How would you describe a situation in which substitution occurs?
Substitution can occur in a great many different situations. Substitution usually occurs when someone is scheduled to teach for example and becomes sick.
Examples of transcoding linear to nonlinear text?
Transcoding linear to nonlinear text is fairly straightforward. Nonlinear text usually refers to text with pictures. To transpose to linear text, simply remove the pictures and rewrite if necessary.
What is the definition of inverse oporation?
An operation usually used in solving equations which is the exact opposite of the original problem in order to isolate the variable. Addition and subtraction are inverse operations. Squaring and square roots are opposites. etc
Is planning linear or nonlinear?
Usually non-linear.Usually non-linear.Usually non-linear.Usually non-linear.
What is a linear system?
A linear system is an equation to find the intersection of two or more lines. The equations are usually expressed with two variables, x and y. I don't know yet, but maybe geometry might have three variables, including z. Basically it's where two lines intersect and the most common ways of solving it are through graphing, substitution, and/or elimination.Presume you mean "linear".These are systems whose parameters vary directly or proportionally. Plotting functions results in straight lines.
Are simultaneous equations on calculator tests?
Usually not.
