Question

1. ifi = where y = 0 and a + 1, what is y in terms of a? (A) y = 2a - 2 (B) y = 2a - 4 (C) y = 2a 1 (D) y = a +1 4

Answer 1

`y\text{ = 2a-2}`

Here, given the equation in the question, we want to make y the subject of the formula;

`\begin{gathered} (2)/(a-1)=(4)/(y) \\ \\ 2\text{ }*\text{ y = 4(a-1)} \\ \\ 2y\text{ = 4a-4} \\ \\ 2y\text{ = 2(2a-2)} \\ \\ y\text{ = 2a-}2 \end{gathered}`
