Example Question #1 : Understanding Polynomial Functions
It took Jack 25 minutes to travel 14 miles, what was Jack's average speed in mph?
* We have to change the time from minutes to hours, there are 60 minutes in one hour.
Example Question #2 : Understanding Polynomial Functions
Let and . Evaluate .
Substitute into , and then substitute the answer into .
Example Question #3 : Understanding Polynomial Functions
Solve the following system of equations:
We will solve this system of equations by Elimination. Multiply both sides of the first equation by 2, to get:
Then add this new equation, to the second original equation, to get:
Plugging this value of back into the first original equation, gives:
