Answer:
Step-by-step explanation:
Given
M = 27 when Y = 16 and X = 9
Required
Find Y when M = 7 and X = 2
We start by getting the algebraic representation of the given statement
Convert the variation to an equation; we have
<em>Where K is the constant of variation;</em>
When M = 27; Y = 16; X = 9, the expression becomes
This gives
Make K the subject of formula
Solving for Y when M = 7 and X = 2
Recall that
Substitute values for K, M and X
Take square of both sides
Make Y the subject of formula
