Question

Form a set of ordered pairs where the first component is a member of $9,10,-12$ and the second component is related to the first as given.

A) Half of the first component

Answer 1

Let $A=\left\{\right.9,10,-12\left.\right\}$ and

The second component $B$ is half of the first component

So, $B=\left\{\right.3,5,-6\left.\right\}$ half of component $A=\left\{\right.9,10,-12\left.\right\}$

Hence, the possible ordered pair $(3,9),(3,10),(3,-12),(5,9),(5,10),(5,-12),(-6,9),(-6,10),(-6,-12)$
