3. Name the multiples in each of the following problems.
a. 5 x 7 = 35
b. 17 x 2 = 34
C. 16 x 4 = 64
d. 11 x 7 = 77

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: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.
