Question

if the value of x and y are negative which of the following values must be positive. (a) x+y (b) x-y (c) x/y

Answer 1

Given data:

Assume the given value of x = -a.

Assume the given value of y= -b.

The expression for the ratio of x/y is,

`\begin{gathered} (x)/(y)=(-a)/(-b) \\ =(a)/(b) \end{gathered}`

Thus, the only ratio of x and y that is x/y is positive.
