Question

10 y is directly proportional to the cube of x. Given that y = 1512 when x = 6, find the equation for the y in terms of x.​

Answer 1

Answer:

${ \tt{y \: \alpha \: {x}^{3} }} \\ { \tt{y = k {x}^{3} }} \\ { \bf{k \: is \: a \: proportionality \: constant}} \\ { \tt{1512 = (k \times {6}^{3}) }} \\ { \tt{k = 7}} \\ { \boxed{ \bf{y = 7 {x}^{3} }}}$
