Question

if y varies as x, and y is 18 when x is 5, which expression can be used to find the value of y when x is 5?

Answer 1

Answer:

Infinitely Many Solutions

Step-by-step explanation:

We just have one simple relation that when x is 5 then y is 18.

There can be infinitely many equations for such a relation.

1) -x + y = 13

2) x + y = 23

3) 18x - 5y = 0

And so on.....
