To subtract vectors, you simply have to subtract correspondent coordinates.
So, if you have

the subtraction is simply

So, in your case, we have

Answer:
A stone is thrown straight up from the edge of a roof, 750 feet above the ground at a speed of 14 feet per second. A) Remembering that the acceleration due to gravity is -32 feet per second squared, how high is the stone 2 seconds later? B) At what time does the stone hit the ground? C) What is the velocity of the stone when it hits the ground?

1. false because they have the same slope and y-intercept so they have infinite number of solutions
2. true
Answer:
Yes. It is a rational number.
Answer: A
Explanation: 1 & 6 has different angle measurements. 6 is obviously bigger than 1 if we properly look at it.
