There are 8 vertices in a rectangular prism. An easy way to remember that is the number of vertices on the 2 end squares when combined, as they are shared with the side faces<span />
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.

Igneous rocks are defined as formations made from solidified lava or magma.
When lava or hot Magma reaches the surface of the earth or a water body it quickly cools down and changes it's from from a hot liquid to a solid rock.
The chemical composition of Igenous rocks can vary depending on their location, cooling time etc.
However, most Igenous rocks contain some or all of the following minerals:
1. Quartz
2. Micas
3. Amphiboles
4. Olivines
5. Pyroxenes
6. Feldspathoids
7. Feldspars
