what would you do in a problem like this:
4-4x _>36 (greater than or equal to) |
|
Definition
| Solve it like you would a normal algebraic problem, subtract 4 from each side then divide. When shading on the line, use a closed dot and shade to the right. |
|
|
Term
| When solving an inequality and graphing the solution (on a line) how do you know when to use a closed dot and when to use an open one? |
|
Definition
closed dot= equal to
open dot = normal |
|
|
Term
| What do you do when you have a compound inequality? |
|
Definition
| Solve each equation on the side of the Or and then graph |
|
|
Term
| how can you tell if a graphing the solution on a line problem is and or or? |
|
Definition
Greater than = Or (greatOR than)
Less than= and (Less thAN-D) |
|
|
Term
| what do you do with an AND problem? |
|
Definition

|
Definition
| set what is in the absolute value symbols to 0 |
|
|
Term
| how do you graph inequalities? |
|
Definition
straight up graph them. Then look at the symbol when drawing the line:
< > is dotted line, equal to is solid
Shade up if its greater than, down if its less thannn |
|
|
Term
| Graph the absolute value inequality? |
|
Definition
It will be a "V" shape and shaded.
greater than shade up
less than shade down |
|
|
Term
| solve each system by graphing? |
|
Definition
| Just plot the points and the point of intersection is your answer. |
|
|
Term

|
Definition
| you have to shade somewhere |
