march 13th

We started off with mental math.

Then we went to www.poly.com and looked at some weird shapes.

Reminder that we are invited to interviews with our parents.

3 types of solutions
1)consistent- on solution (lines cross)
2)inconsistent-no solution(parallel)
3)dependent(ant)-infinetly many solutions-superimposed lines-(on top of eachother)

0=29- NO SOLUTION

0=0,1=1,2=2,etc....-INFINETLY MANY SOLUTIONS
