Hed an additional sheet of paper, if needed. Standard 7.RP. A.2.B: Identify the constant of proportionality (unit rate) in tables, graphs, equations, diagrams, and verbal
descriptions of proportional relationships.
Two relations are described below. Determine whether each describes a directly proportional
relationship or not. If proportional, identify the constant of proportionality.
Relation A: The value of y is equal to the sum of x and 2
Relation B: The value of y is equal to 2 times x
Strategy: Create tables to determine if the relationships are proportional or not

55% are girls and 45% are boys : ) hope this

step-by-step explanation:

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.
