Answer:
The number of miles traveled for x hours
Step-by-step explanation:
There are no statements on your list that describe the roots.
If the discriminant is a negative number, then the two roots
of the equation are complex conjugates. They both have
imaginary parts to them.
This is a proper fraction because the numerator is smaller than the denominator, making it proper.
If it were improper the numerator would be larger than the denominator. If it were a mixed fraction there would be a WHOLE number and a fraction, for example 5 1/2.
I hope this helps! <3
