CP Geo Unit 3 Review Questions

There will be TWO algebraic proofs (section 3.6) on the test so...

DO NOT SOLVE but... Which term is the easiest to solve for first in this system of equations?

 $9x-7y=13$  

 $5x+y=7$  

• 9x

• -7y

• 5x

• y

Solve the system of equations...what is the value of y?

 $x-3y=17$  

 $4x+9y=5$  

• y=3

• y=-3

• y=8

• y=-8

Which option completes this t chart justification.

•  $\angle11\cong\angle12$  

•  $\overline{YZ}\cong\overline{ZX}$  

•  $\angle7\cong\angle8$  

•  $\overline{YX}\cong\overline{ZX}$
