Explanation:</h2>
A system that has one or infinitely many solutions is called <em>consistent. </em>If an equation in a system tells us no new information then the equations of the system are <em>dependent. </em>In other words, to find an equation that creates a consistent and dependent system with the given equation we have to get the same line:
The given line is:

If we multiply both sides of the equation by a constant we will have the same line when plotting, therefore let's multiply by 3:

So a system of two linear equation that is consistent and dependent is:

No because adding the two fives will give you a 10 and 10 is greater than 3
You can use calculus ( related rates). Given the rate os change of the radius for example you can find the rate of change of volume using differential calculus.
