Addition Property of Inequality | a < b then a + c < b+ c |
Multiplication Properties of Inequality | if a < b and c > 0 then ac < bc if a < b and c < 0 then ac > bc |
Solution set for a system | the intersection of the solution sets for the individual sentences. |
Solve the system y = 3x xy = 48 | x(3x) = 48 3x^2 = 48 x^2 -= 16 x= 4 or -4 |
Linear Combination Method | adding multiples of the given equations way of solving systems |
Inverse Matrices | if the product of two matrices are the identity matrix |
System- Determinant Theorem | a 2 x 2 system has exactly one solution if and only if the determinate of the coefficient matrix is not zero. |
