Help ME

no c is the answer of question no 5

2. A= Constants

3 and 4 Idk

5. A= (3+4)+5=3+(4+5)

6. Didn't learn yet but, either it is, A or D, I think D

1.4

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

answer: 1) twenty-seven times y

              2) twenty-seven multiplied by y
