1. FIRST QUESTION.</h2>
M is directly proportional to
Suppose you have two variables, say, . We say that varies directly as or, in other words, is directly proportional to if and only if:
Where is a nonzero constant called the constant of proportionality.
Knowing this, we can solve this problem. Here is directly proportional to . So:
We know that when , hence the constant of proportionality can be found as follows:
So:
<h3>PART A)</h3>
When , then:
<h3>PART B)</h3>
When , then:
<h2>2. SECOND QUESTION.</h2>
M is directly proportional to
We know that when , hence the constant of proportionality is:
So:
<h3>PART A)</h3>
When , then:
<h3>PART B)</h3>
When , then:
