Question

Assume that AB is parallel to EC, es press y in terms of x

Answer 1

Knowing that AB is parallel to EC, we can say that the proportion between DC and CB is equal to the proportion between DE and EA. Then:

`(DC)/(CB)=(DE)/(EA)`

Finally, we replace each value:

`\begin{gathered} (y)/(8)=(6)/(x) \\ y=(6\cdot8)/(x) \\ \therefore y=(48)/(x) \end{gathered}`
