Distributive Property: Know how to distribute by multiplying what's on the outside of the parentheses to the items inside the parentheses separately. For example, 3(6 + 2) is distributed as 3(6) + 3(2), which gives us 18 + 6 = 24.
Simplifying variable expressions: Remember to:
1) Change any subtracting to adding a negative
2) Combine like terms
For example: To simplify 2x + 3y - 2y + 7, we first rewrite the expression without subtraction:
2x + 3y + -2y + 7
Then, combine like terms:
2x + y + 7
Solving Equations: This is the big one! Remember to do the opposite to both sides in order to get the variable by itself! Check out previous examples in the blog. Just type "equations" in the search bar, top left, and several posts will come up. Look back through your notes and examples.
Inequalities: Study your notes on inequalities - graphing AND naming them from a graph. Remember that a closed dot is used to indicate a possible solution, while an open dot is used to indicate a non-solution.
