The cycles within which earth's matter moves are closed systems. This means nothing is gained or lost from the system; it only changes from one form to the other. The total amount of matter on earth remains the same. Using tectonic plates as an example, divergent boundaries occur where new oceanic crust is being created. New crust is being created and simultaneously the same amount of crust is being destroyed at convergent margins.
The contrapositive of the conditional statement is option d: If the graph of two variables is not a linear function, then the two variables are not directly proportional.
<h3>What is the statement about?</h3>
To known a statement that is contrapositive, you will need to negate the hypothesis as well as the conclusion of the statement, and also switch their positions.
Hence:
- If two variables are directly proportional, so their graph is a linear function.
- If two variables are not directly proportional, so their graph is not a linear function.
Therefore, The contrapositive of the conditional statement is option d: If the graph of two variables is not a linear function, then the two variables are not directly proportional.
