Learn how to solve linear equations that contain a single variable. For example, solve 2(x+3)=(4x-1)/2+7. Learn for free about math, art, computer programming, economics, physics, chemistry, biology, medicine, finance, history, and more.
Which says the absolute value of x equals: x when x is greater than zero. 0 when x equals 0. −x when x is less than zero (this "flips" the number back to positive).

SYSTEMS OF EQUATIONS in THREE VARIABLES. ... A linear equation in three variables describes a plane and is an equation equivalent to the equation
Exponential Equations An exponential equation is one in which a variable occurs in the exponent, for example, . When both sides of the equation have the same base, the exponents on either side are equal by the property if , then .
Factoring Quadratics. ... one of the big benefits of factoring is that we can find the roots ... Derivation of Quadratic Equation Quadratic Equation Solver Algebra ...
Graphing Quadratic Equations. A Quadratic Equation in Standard Form. (a, b, and c can have any value, except that a can't be 0.) Here is an example: You can graph a Quadratic Equation using the Function Grapher, but to really understand what is going on, you can make the graph yourself.
Graphing Systems of Equations. This is the first of four lessons in the System of Equations unit. We are going to graph a system of equations in order to find the solution. REMEMBER: A solution to a system of equations is the point where the lines intersect! Prerequisites for completing this unit: Graphing using slope intercept form.
The study of linear algebra first emerged from the introduction of determinants, for solving systems of linear equations. Determinants were considered by Leibniz in 1693, and subsequently, in 1750, Gabriel Cramer used them for giving explicit solutions of linear systems, now called Cramer's Rule.
Another special type of linear function is the Constant Function ... it is a horizontal line: f(x) = C No matter what value of "x", f(x) is always equal to some constant value.
In "real life", linear programming is part of a very important area of mathematics called "optimization techniques". This field of study (or at least the applied results of it) are used every day in the organization and allocation of resources.
Logarithms Can Have Decimals. All of our examples have used whole number logarithms (like 2 or 3), but logarithms can have decimal values like 2.5, or 6.081, etc.
You can also divide polynomials (but the result may not be a polynomial). Degree. The degree of a polynomial with only one variable is the largest exponent of that variable.

The name Quadratic comes from "quad" meaning square, because the variable gets squared (like x 2).. It is also called an "Equation of Degree 2" (because of the "2" on the x)
Or we can use the special Quadratic Formula: Just plug in the values of a, b and c, and do the calculations. We will look at this method in more detail now.
Solving Radical Equations. How to solve equations with square roots, cube roots, etc. We can get rid of a square root by squaring. (Or cube roots by cubing, etc) But Warning: this can sometimes create "solutions" which don't actually work when we put them into the original equation.

Relational algebra received little attention outside of pure mathematics until the publication of E.F. Codd's relational model of data in 1970. Codd proposed such an algebra as a basis for database query languages.
In physics texts, these periodic, sinusoidal graphs are generally divided into two distinct categories determined by the units used on the x-axis. Each category has a specific vocabulary. Graphs with equations of the form: y = sin(t) or y = cos(t) are generally called vibration graphs.
What are the period and frequency of y = sin(2x)? The 2 has the effect of shortening the wave length or period. Waves appear on the graph twice as frequently as in y = sin(x). The graph shown below uses a WINDOW of X: and Y: (-2, 2, 1). There are 6 complete waves in a distance along the x-axis of .
