Question

which equation represents a proportional relationship that has a constant of proportionality equal to 0.7

Answer 1

Thus x , y /  = 7 /10 and x.y = 7 / 10 represents a proportional whose relationship has constant of proportionality equal to 0.7

Step-by-step explanation:

Given: Constant of proportionality is 0.7

We have two types of proportionality

1. Direct: One variable directly proportional to another variable. (y=kx)

2. Indirect: One variable inverse proportional to another variable. (y=k/x)

where, k=0.7 or 7/10

So, Possible equations

Direct relation y = 7 /10 x , y /  = 7 /10

Inverse relation y = 7 / 10 x , xy = 7 /10

Hence,   and  represent a proportional whose relationship has constant of proportionality equal to 0.7

Thus x , y /  = 7 /10 and x.y = 7 / 10 represents a proportional whose relationship has constant of proportionality equal to 0.7
