Two examples are shown here, one relatively easy, then one with some fractions involved.

|
Demonstrates how to solve for a variable under the radical that needs to isolated first after entering the given value for the other variable in a formula.
|
|
Describes how to approach solving a radical eqaution, then demonstrates the stepss needed. It finishes with a check of the answers, stressing that this is an essential step.
|
|
Shows how to substitite the given value for the output variable, then rearranges the resulting equation in standard form. Values for a, b, and c are identified and then entered into the quadratic…

The informaton given here can be entered directly into the y = mx + b or slope-intercept form. Then the y-intercept is used as a starting point where you apply rise over run to the given slope to…

|
Another demo on how to use the y-intercept to start a graph of a linear equation and then use the slope to find other points on the graph. It finishes with showing the line representing all of the…

|
A demo that shows how to substitute possible x-y ordered pairs into an equation to find out whether they create a true statement, determining which are solutions and which are not.
|
|
This explains how to use the slope and y-intercept to determine points on the line graph of a linear equation in two variables and then draws the straight line graph.
|
|
Presents a compound inequality where both sides have to be solved for the variable first, and then shows how to graph the simplified results
|
|
This contains one example of solving an inequality as described in the title.
|
|
A quick demonstration of how to interpret a line graph of a compound inequality and write its algebraic form.
|
|
An examplel of how to rearrange a formula to better suit its particular purpose. Often we need to do this because it is easier to rearrange it once instead of having to solve for a variable each…
|
|
A somewhat fancierversion of seveal solving equation versions that should help solidify the process in your mind.
|
|
This describes how integers interact when combined, treating minus signs as a negative sign on the number and thinking that all of the integers are being added with negatives and postives working in…
|
|
Two examples that show different possible results from solving a radical equation. You must always check the answer to these.
|
|
Shows how these forms are interrelated
