Question

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

A) Half of the first component

Answer 1

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

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

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

Order pair is the combination of components of $A$ and $B$

Hence, the ordered pairs are $(3,9),(3,10),(3,-12)(5,9)(5,10),(5,-12),(-6,9),(-6,10),(-6,-12)$
