Answer:
x = 400 when y = 100
Step-by-step explanation:
This is a question in relation to direct variation.
y ∝
y = k
Given that, y = 45, x = 81. Then;
45 = k
45 = 9k
k =
k = 5
Thus the relationship among the variables is;
y = 5
If y = 100, then;
100 = 5
=
= 20
x =
x = 400
Therefore, x = 400 when y = 100.
