Remember the quadratic formula determinant?
If b^2 -4ac < 0, a complex root exists.
So for this problem, m^2 - 4q is the determinant, and if less than 0, is complex.
So a=-m/2 and b=(1/2)SQRT(m^2 - 4q)
Yes, I believe so.
Hope this helps
The value of the 1 in 16,403 is 10,000. It's in the ten thousands place. It tells you there is one set of ten thousand.
Subtract 5x and add 3y from the left side so that it can be moved to the right side. This will allow you to solve and get the second equation.
100 miles ............... 2 hours
x miles ................1 hour
x = 100 m / 2 h = 50 m / h
