Question

Use the given information to find the unknown value Y varies directly as x when x =2 y=14 find y when x =22

Answer 1

Step-by-step explanation:

The initial statement is

`\begin{gathered} y\infty x \\ y=kx \end{gathered}`

when x = 2, y = 14

`\begin{gathered} y=kx \\ 14=k(2) \\ k=(14)/(2) \\ k=7 \end{gathered}`

the law connecting y and x

`y=7x`
`\begin{gathered} y=7x \\ \text{when x= 22} \\ y=7(22) \\ y=154 \end{gathered}`

Hence the value of the unknown x = 154
