Here is another example, and one using a variable:2. solve. write your answer in set builder notation and interval notation.

y is less than or equal to ashio-midori.com the slope, if it exists, of the line containing the points (-3,8) and (2,-7). Write your solution using set builder notation asked Aug 18, in Algebra 1 Answers by anonymous | views solve -8(x – 3) > x + 8.

write your solution using set builder notation.

Set-Builder Notation looks like this: { x | x ≤ 2 or x >3 } On the Number Line it looks like: Using Interval notation it looks like: (−∞, 2] U (3, +∞) We used a "U" to mean Union (the joining together of two sets).

In roster form, D will be a list of whole numbers less than 3. These numbers would be 0, 1, and 2. In builder notation, a variable is listed with its limiting number/5(7).

Intersection of sets. The intersection of two sets A and B is the set consisting of all elements that occur in both A and B (i.e. all elements common to both) and is denoted by A∩B, A · B or AB.
