Simultaneous equations are two linear equations that can be solved using bar models. By remembering that the same letter will always have the same value we can work out the missing values. To solve ...

Last time I wrote about new data that overturns the standard cosmological model. Before anyone starts dusting off their ...

Abstract: The solution of a linear system of equations constitutes an important part in the field of linear algebra that is widely used in industries like aerospace, aeronautics, solid mechanics, ...

If the discriminant (b² - 4ac) is negative, the roots are complex numbers. Complex roots always come in conjugate pairs (a + ...

Statement 1: A rational function has a vertical asymptote where the denominator is zero. The denominator x - 2 = 0 when x = 2. Therefore, f (x) has a vertical asymptote at x = 2. The statement is true ...

We have looked at how to solve equations with one unknown value, but what happens when there are two unknown values? An equation with two unknown values will have infinitely many solutions. or \(x=100 ...
