How to find a common difference?
To find the common difference (d), subtract any term from one that follows it *Slope and common difference are the same Step 1- List A1 Step 2- Determine An-1 (common difference, + OR -) Step 3- Add or subtract the difference to the 1st term to get the 2nd term Step 4- make sure to label your terms A1, A2, A3, until you get to the 7th term |
division on both sides of an inequality with a negative number produces an equivalent inequality if the inequality symbol is reversed. To solve a multi-step inequality you do as you did when solving multi-step equations. Take one thing at the time preferably beginning by isolating the variable from the constants.

literal equation is an equation where variables represent known values. Literal equations allow use to represent things like distance, time, interest, and slope as variables in an equation.

{(2, –3), (4, 6), (3, –1), (6, 6), (2, 3)}The above list of points, being a relationship between certain x's and certain y's, is a relation. The domain is all the x-values, and the range is all the y-values. To give the domain and the range, I just list the values without duplication:
domain: {2, 3, 4, 6} range: {–3, –1, 3, 6} |
