Answer:
Step-by-step explanation:
1= divide -8 by 3
2= multiply your answer from one by 2
3= then you have 2/3 of negative 8 (rembere to keep it negative)
Answer:
The point (3, 3) is not a solution of the first equation, therefore is not a solution of the given system of equations.

Step-by-step explanation:
Let V = the launch velocity
Let θ = the launch angle
Let d = the horizontal distance traveled
Ignore air resistance.
The horizontal component of velocity is
u = V cos θ
The time of flight is
t = d/(V cosθ) = (d/V) secθ
Create a table of θ versus t as shown below.
θ t/(d/V)
---- ----------
45 1.4142
40 1.3054
35 1.2208
30 1.1547
The graph shows that as the launch angle decreases below 45°, the time of flight decreases.
Therefore arrow b (θ < 45°) arrives first.
Answer: Arrow b arrives first.
