is the relation {(1, 3), (-4, 0), (3, 1), (0,4), (2, 3)} a function? why or why not?
answers:
a)yes, the range value 3 corresponds to two domain values, 1 and 2.
b)yes, there is no value in the domain that corresponds to more than one value of the range.
c)no, the range value 3 corresponds to two domain values, 1 and 2.
d)no, there is no value in the domain that corresponds to more than one value of the range.

tangent

step-by-step explanation:

my guess is

step-by-step explanation:

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.
