Sagot :

Answer:

A

Step-by-step explanation:

Given that 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 = 7 when x = 3 , then

7 = 3k ( divide both sides by 3 )

[tex]\frac{7}{3}[/tex] = k

y = [tex]\frac{7}{3}[/tex] x ← equation of variation

When x = 7 , then

y = [tex]\frac{7}{3}[/tex] × 7 = [tex]\frac{49}{3}[/tex]
