True or false, depending on the specifics. True, because the gravity makes it go to the ground. False, because gravity is always working, so you don't need to throw the ball. However since it doesn't say that it only happens when you throw it. The answer should be true.
4. because it is reduced and the simplest to understand
(7,1) is the correct answer
Answer:
Step-by-step explanation:
Let's reformat both equations so that 
is by itself on each side:
Since we isolated to one side in both equations, we know the right-hand sides must be equal:
Solving for 
will give us the x-coordinate of the point of intersection:
Plugging in this x-coordinate to either of the above equations will give us the y-coordinate of the point of intersection:
Therefore, the point of intersection is 
Multiply than divide by 1
