Answer:
One car was going 45 mph and the other was going 55 mph
Step-by-step explanation:

Both the given lines in graph intersect at point (5 , -2), the point must satisfy both the equations.
and if we check the options, we will observe that D. option has both the equations that satisfy the given conditions.
that is ~

put y = - 2,we will get :


so, 1st equation satifys the condition. let's check out 2nd one.

put y = -2



Hence, we can conclude that the Correct choice is D

I am not 100% sure but I think the answer is C I hope I helped you and Good luck
In statistics, the amount of degrees of freedom is
the quantity of values in the final computation of a statistic that are free to
differ. In this case, you can get the answer by adding the number of bags
and subtracting 1.
So in computation, this would look like: 3 + 2 + 1 + 2 - 1 =
7
Therefore, 7 is the degrees of freedom.
