Addition Property of Inequality | if 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 |
How is the solution determined looking at data? | The intersection (or the same number for both domain and range) or where two lines in a graph meet. |
Substitution | y=3x x(3x)=48 xy=48 x=4 |
Consistent | one or more solutions |
Are parallel lines consistent? | no, they never intersect so they have no solutions and known as inconsistent. |
Linear Combination | Ax=By |
System-Determinant Theorem | a 2X2 system has exactly one solution if and only if the determinant of the coefficient matrix doesn't = zero |
