Linear functions are fundamental building blocks in mathematics and play a key role in solving real-world problems where the rate of change remains constant. Linear functions arise in a wide range of ...

Solving linear inequalities Inequalities are generally solved using the same steps as for equations, except when multiplying or dividing both sides of an inequality by a negative number, in which case ...

Example 2.2 The augmented matrix associated to the system 2x+3y = 0 4x−7y = 2 2 x + 3 y = 0 4 x 7 y = 2 is (2 3 0 4 −7 2) (2 3 0 4 7 2) Suppose we have a matrix equation Ax = b A x = b, where x x is a ...

Equations and identities An equation is a statement with an equals sign, stating that two expressions are equal in value, for example: \ (3x + 5 = 11\).

Capture relationships between data sets by graphing linear equations in Microsoft Excel 2007. Linear equations allow you to predict values within your data set and view the overall trend.

We can plot linear equation as follows: The graph of this equation is a line. We also plot the graph of higher order equations such as Quadratic equation: Cubic equation: And higher order equations.

Linear and nonlinear models are two types of mathematical functions that can be used to describe the relationships between variables. In this article, you will learn what they are, how they differ ...

Equations and identities An equation states that two expressions are equal in value, eg \ (3x + 5 = 11\). Solving an equation means finding the value or values for which the two expressions are equal.
