2 Draw a line from each system of linear equations to the correct description of the
solution to the system.
y= 2x + 7
2x = 7
no solution
V + 4x = 5
2y = -8x - 20
exactly one solution
IN
D
infinitely many solutions

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3

statement #3: proof- ang is congruent to ang ecd : angles are congruent.  

step-by-step explanation:

1: the missing angles in statement #3  

a.) acb  

reason- the reason why the answer is acb is because angle ecd and angle acb are both the same size *that's what the word congruent means this is really simple.  

2: the missing word in reason #3  

c.) vertical  

reason- the reason why the answer is vertical is because the angles in that diagram on figure 2 is slanted, which is vertical, and the e and a both lay on vertical lines. along with the other's, but e and a are the 2 main points you want to focus on. and c is kind of like your starting point, because c is for both angles, not just one.  

i hope that was and understanding.
