You can put this solution on YOUR website!
This \"stuff\" is algebra!
\n" ); document.write( "The topic is \"variations\"
\n" ); document.write( "When one quantity varies (changes) as a result of a change in another quantity, you can write the equation of variation that shows this relationship.
\n" ); document.write( "A simple example might be a person's salary depends on how many hours he/she works. The more hours worked, the more salary is earned, right?
\n" ); document.write( "This is called a \"direct\" variation because, as the hours worked go up, the salary goes up. This is usually stated as:
\n" ); document.write( " The salary \"varies directly\" as hours worked. Notice that the salary does not equal the hours worked.
\n" ); document.write( " So you cannot write: S = H, rather, you would write: S = kH, the k is called the constant of variation.
\n" ); document.write( "Another example would be the more you exercise, the less you weigh (hopefully).
\n" ); document.write( "This is called an \"inverse\" variation because as the number of hours of exercise go up, the weight goes down.
\n" ); document.write( "This can be stated as: The weight \"varies inversely\" as the hours of exercise.
\n" ); document.write( "Again, notice that the weight is not equal to the inverse of the number of hours exercised so you cannot write W = 1/H, rather, you would write W = k/H where, k is the constant of variation.
\n" ); document.write( "Now to your problem:
\n" ); document.write( "\"y varies directly as x (
\n" ); document.write( "You can combine these two statements into one equation but you will use only one constant of variation, k.
