A quick example of distributing an external exponents to all factors in a rational expression
|
|
|
An example of how we distribute an exponent outside of parentheses to all factors within.

|
This talks about why we need two equations to solve for two unknown values, and then demonstrates how to add two equations together to eliminate one varaible and solve for the other one, then find…

|
This shows the method of using the point-slope form to write the equation, then solving that form for y to get y = mx + b.
|
|
|
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 contains one example of solving an inequality as described in the title.
|
|
|
Shows one example of solving a iinear inequality in two steps.
|
|
|
A demo that only shows a one step process of adding an integer to both sides of an inequality so that the variable stands alone and we can tell what values are true for that inequality.
|
|
|
This demo takes some thought so you may want to watch it a few times to fully understand. Writing the expression and then we simplify it so that it is more usable in future.

|
This shows how to represent the two unknowns using their given relationship so that a linear equation can be written using one variable. Then that equation is solved to answer the question
|
|
|
This describes the way to represent a series of consecutuve integers, then consecutive odd or even integers so that you can w rite an expression that combines them.
|
|
|
Shows how to take the descriptive set builder notation and write a roster set to represent the same one.
|
|
|
This video demonstrates how to change a description in words into an algebraic expression.
|
|
|
This describes the process of solving for a particular variable in terms of other variables in an equation. There is a need to go further to combine like terms before it is complete.
|
|
|
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…
