Find the constant variation for xy=12

The expression given to us is:

If we divide both sides by then the above expression can be rewritten as:

Now, we know that 12 is a constant, so the above equality can be changed into a proportionality as:

Thus, we now know that there is an inverse proportionality between and which has a constant of proportionality, also known as the constant of variation to be 12.

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.

step-by-step explanation:

all group life insurance is term insurance. actually it is annual renewable term and it is rated on the average age and claims experience of the entire group, which is called "experience rating." remember, this type of insurance has a 31-day grace period and is convertible to whole life upon leaving employment. a contributory group plan requires that both the employer and the employees pay part of the premium. at least 75% of those eligible must participate, so the group is sure to get most of the healthy employees as well as those that are sick.
