Answer:
constant of variation k = 10 when y=12 and x = 1.2
Step-by-step explanation:
We are given If y varies directly as x, and y is 12 when x is 1.2, what is the constant of variation for this relation?
y = 12
x = 1.2
Constant of variation = k = ?
We know that if y varies directly as x then:
We need to find k:
Putting values:
So, constant of variation k = 10 when y=12 and x = 1.2
