side.
Who is correct? Explain.
Tomas is correct; AC is opposite ZB and BC is adjacent to 2B.
Iliana is correct; BC is opposite ZB and AC is adjacent to ZB.
Both are correct because both AC and BC are opposite 2B.
Neither is correct because neither AC nor BC is opposite ZB.

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3

step-by-step explanation:

first, eliminate the parenthesis:
