The distance Train A travels is represented by
where d is the distance in kilometers and t is the time in hours
The speed of train A is 70 kilometer per hour
To find speed of train B use the table
find out slope
The speed of train B is 75 km per hour
The speed of the train B is more
Train B is going faster
Answer:
Step-by-step explanation:
for vertex
x-2=0 gives x=2
when x=2,y=4
vertex (2,4)
axis of symetry
x-2=0
The difference between the coefficients 7 and 3 is 4, so one solution is
y = 1, x = -1.
Then the remaining solutions will be of the form
x = -7n-1
y = 3n+1
for some integer n.
_____
Some of the solutions are (for n=0, -1, -2, 1, 2)
(x, y) = (-1, 1), (6, -2), (13, -5), (-8, 4), (-15, 7)
Answer:
Its length is 3/8× 24 = 9 ft.
So correct option is A.
I hope this helps you.
