Matrix: a rectangular array of quantities or expressions in rows and columns that is treated as a single entity and manipulated according to particular rules.
Feasible Region: an area defined by a set of coordinates that satisfy a system of inequalities.
Substitution: method of solving a system of equations where in one of the equations is solved for one variable in terms of the other variables.
Elimination: a method of solving an equation involving two or more variables where one of the variables is expressed as a function of one of the other variables.
Matrix Row Reduction: A matrix is in row echelon form (ref) when it satisfies the following conditions. The first non-zero element in each row, called the leading entry, is 1.]]> 2016-10-04 17:24:04 UTC https://padlet.com/griffithsa4855/nza0goaxmf1m/wish/128265710 Linear Inequalities griffithsa4855 https://padlet.com/griffithsa4855/nza0goaxmf1m/wish/128273696 A linear inequality is an inequality (where it has a greater or less than sign) and it forms a straight line. ]]> 2016-10-04 17:40:20 UTC https://padlet.com/griffithsa4855/nza0goaxmf1m/wish/128273696 Feasible Region https://padlet.com/griffithsa4855/nza0goaxmf1m/wish/128685633 Where two inequalities have the same points in the solution. When you shade them both, the spot where they are both shaded is feasible region ]]> 2016-10-06 04:38:25 UTC https://padlet.com/griffithsa4855/nza0goaxmf1m/wish/128685633 Reduced row Reduction.

Of solving with multiple variables and equations. 


If you look up , Gaussian Elimination by Patrick JMT, on YouTube u will find a video on how to solve row reduction. It's really helpful and a great way to study for the tests ]]> 2016-10-06 04:48:26 UTC https://padlet.com/griffithsa4855/nza0goaxmf1m/wish/128686271 elimination https://padlet.com/griffithsa4855/nza0goaxmf1m/wish/128687592 methods of solving equations with multiple variables.
