WebSuppose y varies directly as x. Then, we can say y = kx where k is constant. We know that y = 12 when x = 4. We can use that information to solve for k. 12 = k(4). So, k = 3. We … WebSep 3, 2024 · The required answers are,. The constant of proportionality k if y = 13 when x = 8, k = 36.77.; The variation equation in terms of x is x = k²/y²; The k from above if x = 27 then y = 7.21; What is constant of proportionality?. The constant of proportionality is the ratio of two proportional values at a constant value.. Now it is given that,. y is inversely …

If y=3 when x=7, find y when x=9. Solution. First, let's find k, the constant of proportionality. We already know that x varies directly with y and that y=3 when x=7. We can use that to find k. y=kx3=k77⋅3=k7⋅721=k. Now that we know k=21, we can find y when x=9. y=kxy=219y=73 shop 428
