Answer:
y = 49
Step-by-step explanation:
Given y varies directly as x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 21 when x = 6 , then
21 = 6k ( divide both sides by 6 )
3.5 = k
y = 3.5x ← equation of variation
When x = 14 , then
y = 3.5 × 14 = 49
