Question

Write the equation of variation. Solve for the unknown variable/s. Kindly show your complete solution.
1. y varies directly as x. and y=9 when x is 15. find y when x= 24.
2. y varies directly as a square of x. and y=18 when x is 3. find y when x= 6.
3. a varies inversely as b squared, a=2 when b =3. find a when b is 2..
4. if y varies inversely as x, and y is 24 when x is 16. find y if x is 19.
5. y varies directly to the square of x and z. y= 5 when x =2 and z =10. find y if x = 4 and z =5.
6. l varies directly to m and inversely to n, l=10 when n=5 and m =20. Find l if m=4 and n =2.
