Find the constant of variation:
a. x 1 2 3 4
y 6 3 2 1.5

b. x 1 3 4 24
y 24 8 6 1

a. 6

b. 24

Step-by-step explanation:

a and b are both inverse constant variation

a.  x * y = K      

1 x 6 =6

2 x 3 = 6

3 x 2 = 6

4 x 1.5 = 6

k = 6

b. 1 x 24 = 24

3 x 8 = 24

4 x 6 = 24

24 x 1 = 24

K = 24

1e+27

step-by-step explanation:

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
