1) for the data in the table , does y vary directly with x? If it does, write an equation for the direct variation. X[8, 16, 24] Y[[13, 26, 39]
2) X[32,16,8] Y[24,8,6

2) X[32,16,8] Y[24,8,6

danjs · Answer

If y varies directly with x, then there is some constant or proportionality that relates y to x.

y = k*x

k = y/x

For each y/x, there should be the same constant k.

13/8 = 1.625

26/16 = 1.625

39/24 = 1.625

The first one is a direct proportionality...

DO the same for the next part.
