Answer:
(2, -2)
Step-by-step explanation:
Solve 7x - 2y = 18 for x:
Substitute 2/7y+ 18/7 for x in -4x + 3y = -14
Substitute -2 for y in x = 2/7y + 18/7
Given that x = 2 and y = -2, the point is: (2, -2)
Therefore, the solution is (2, -2).
Answer: 6.06 seconds
This will not factor. The ball will hit the ground 6.06 seconds after thrown.
