How fast is the ball seem to be moving?
This question illustrates relative velocity;
Since the ball and the train moves in the same direction, the required velocity relative to the person standing behind is:

i.e. we add both velocities


The answer is D. when an exponent on the outside you multiply the exponents
2y + 4 + 5y + 8=
7y + 4 + 8=
7y + 12=
Answer:
y=-1/2x+2
Step-by-step explanation:
slope is -1/2 beware this is a negitive slope so it goes down like this \
go one up and go to the left 2 times and connect the dots
Distribute the -2 to get
-16x + 8 < 2x + 5
3 < 18x
1/6 < x
so x > 1/6
