Discriminant b^2-4ac = (-9)^2 - 4*2*9 = 9
so there are 2 roots
because of the -9x and 9 they will both be positive
It would be: 15/7 = 2 1/7
Answer:
True
Step-by-step explanation:
since, S= D/T the distance traveled would only be 100m, it is a consatnt variable dividing it with the time it takes to reach that distance would be its speed. Unless there is an acceleration happening in that process the speed would change depending on the situation.
