Linear functions are used to model a broad range of real-world problems. The ability to solve linear equations and inequalities is an essential skill for analysing these models. This section covers ...

Save guides, add subjects and pick up where you left off with your BBC account. A function machine is a way of writing rules using a flow diagram. The equation \(3j - 6 = 9\) can be shown on a ...

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.

Show students the graph of a linear function and help them identify the slope by looking at the steepness of the line. Then, ask them to find the slope of the linear function by using its equation. 3.

Some equations are beautiful because they reveal unexpected relationships between different subjects. The Loewner differential equation, introduced by Charles Loewner in 1923, describes the time ...

Simultaneous linear equations are used to model situations where two relationships must be satisfied at the same time. These problems often involve two interdependent variables, such as comparing ...

A function machine is a way of writing rules using a flow diagram. The equation \(3h - 6 = 9\) can be shown on a function machine by writing out the functions that have been applied to \(h\) in ...
