Poll

Learning Target: I can apply my knowledge of arithmetic sequences, systems of equations, and systems of inequalities to solve problems.

Rate your current state of understanding of the learning target.

• 4 - I could teach it!

• 3 - I understand it.

• 2 - I'm getting there.

• 1 - I don't understand, I need some more help/practice.

It's review time!

Work hard now so you feel good about your test next week :)

Multiple Choice

Is this sequence arithmetic?

5, 10, 25, 35, 40, 45, 55,...

• Yes, each term differs by a common difference

• No, there is no common difference.

Multiple Choice

Write the definition of the following arithmetic sequence: 1, 5, 9, 13, 17, 21,...

(General Explicit definition:  $a_n=a_1+d\left(n-1\right)$  , where  $a_1$  is the first term of the sequence and  $d$  is the common difference between terms.)

•  $a_n=1+4\left(n-1\right)$  
  

•  $a_n=4+\left(n-1\right)$  
  

•  $a_n=1+21\left(n-1\right)$  

•  $a_n=21+4\left(n-1\right)$  

Multiple Choice

Is  $\left(3,\ 7\right)$  a solution to this system of equations? 

 $y=x+4$  

 $-x+y=19$  

• Yes, this is the intersection point of the system of equations.

• No, this point is not a solution to both equations so it not a solution to the system.

Multiple Choice

Find the solution to the system of equations:

 $-x+y=19$  

 $y=x+4\$  

• (0, 19)

• (0, 4)

• No solution

• Infinitely many solutions

Multiple Choice

Which section shows the set of solutions to the system of inequalities.

• 1

• 2

• 3

• 4

Multiple Choice

True or False: The point (3, 1) is a solution to the following system of inequalities.

 $y<x+4$  
 $x+y\ge4$  

• True, the point is a solution to both inequalities therefore it is a solution to the system.

• False, the point is not a solution to both inequalities. 

Move to Google Classroom and complete your exit ticket.

Enjoy your weekend, I will see you in February :)
