Which expression represents the multiplicative inverse of -9/7? A. -7/9
B. 9/7
C.7/9
D.-9/7

i believe the answer would be C

Step-by-step explanation:

im pretty sure you just need to flip the order around so the answer would be 7/2?

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
