Solving Multi-Step Equations
... Sometimes one side of an equation has has a variable expression as the numerator of a fraction. With this type of equation, it may help to first multiply both sides of the equation by the denominator. ...

Elimination using Multiplication
... Adding or Subtracting the equations will not eliminate a variable. Therefore, we must multiply one or both equations to change the coefficients to enable elimination. Since the first equation has “–y” and the second equation has “+4y,” multiply the first equation by 4. ...

Linear Functions
... We represent this fact by graphing with a ________________ line. Finally, it can be shown that the solution to an inequality in two-variables is a half-plane, which is one side of the line or the other. Pick a point on either side of the line, use (0, 0) when you can. Test it in y > 2 x−3 ... 0 > 2( ...

Chapter 3 Review
... Section 3.3: Graph Systems of Linear Inequalities Key things to remember: 1. Just like when graphing equations, solve for y, identify the y-intercept, identify the slope. 2. Graph the inequalities on the same graph. Check whether the lines are solid or dashed. 3. Then Shade each line either above o ...

The Discriminant and Complex Numbers
... The discriminant allows us to describe the nature of the roots of a quadratic function without actually finding the roots. When one describes the nature of the roots, they are describing two things: i) how many roots the function has (1 or 2) ii) the kind of roots that they are (real or imaginary) T ...
