Answer:
(0,-8)
x=0
y=-8
Step-by-step explanation:
There are a couple of ways you can solve this I used what I think is called the elimination method
We first start by writing the equations in linear form (y=mx+b)
For the first one we have -12x-5y=40
we add 5y to both sides and subtract 40 to get
-12x-40=5y
divide by 5 to get
-12/5x-8=y
Then the second one we have
12x-11y=88
same deal here, add 11y and subtract 88 to get
12x-88=11y
divide by 11 and get
12/11x-8=y
We then set the two equations equal to each other and get
-12/5x-8=12/11x-8
We can add 8 to both sides and get
-12/5x=12/11x
Just by looking at it you can see that the only solution for x is 0
Plug in 0 to the first equation and get -12*0-5y=40
This means that -5y=40
Solve for y and get -8

Answer:
9 seconds
Step-by-step explanation:
d=-16t²+vt+h
The water level will be at 0 level (distance = 0)
0 = 16t² - 90t - 486
8t² - 45t - 243 = 0
(t - 9) (8t + 27) = 0
t = 9 or t = -27
since time should be a positive number, so t = 9 second
