Answer:
x = -4 y = -1
Step-by-step explanation:
x + 4y = -8
4y = -x - 8
y = -1/4x - 2
6x - 2(-1/4x - 2) = -22
6x + 1/2x + 4 = -22
13/2x + 4 = -22
13/2x = -26
x = -4
(-4) + 4y = -8
-4 + 4y = -8
4y = -4
y = -1
Answer: One solution at ( -4, -22 )

Answer:
I believe it is 100 ft
Step-by-step explanation:
For this case we have the following equation:
h (t) = - 12t2 + 36t
When the object hits the ground we have:
- 12t2 + 36t = 0
We look for the roots of the polynomial:
t1 = 0
t2 = 3
Therefore, the time it takes the object to hit the ground is:
t = 3 s
Answer:
the time when the object hits the ground is:
t = 3 s
