1. Math Talk: Mental computation
Sort the systems in order of least solutions. Then solve.
A −6𝑥−2𝑦+6𝑧=−8 3𝑥+4𝑦+12𝑧=8 6𝑥+2𝑦−6𝑧=−18
B −5𝑥−7𝑦+3𝑧=−5 15𝑥+21𝑦−9𝑧=15 10𝑥−14𝑦+6𝑧=−10
C −3𝑥−𝑦−3𝑧=−8 −5𝑥+3𝑦+6𝑧=−4 −6𝑥−4𝑦+𝑧=−20

4. Routines for turning in homework (turn in online – go to clever: https://clever.com/in/luhsd
Check the answers to your homework with my notebook and online at clever. This is not a time to mark your paper, but just to do a quick check and check for understanding for yourself.
Label your homework with your name, homework number and the page and exercises assigned at the top.
Turn in your paper on the folder labeled “homework #7”
Have a seat when you are done and take out your student journal, we will continue any exercises we didn’t finish from the day before.

5. How did it go?
“Printing Tickets” 

10. Characteristics of a Quadratic Equation
Vertex can either be
Maximum Point
Minimum Point
The Parabola is increasing to the right of x coordinate vertex
The Parabola is decreasing to the left of x coordinate vertex

11. Vertex
Vertex Form
Standard Form
Intercept Form

16. Example: Calculate the vertex, max or min value, domain and range
Example: Calculate the vertex, max or min value, domain and range. Also, create a table with 5 points.
