Answer:

Step-by-step explanation:

No if it was, the football would keep going up forever and keep going up faster as it was released
physics and common sense tells us that there is air resistance to slow the rise of the football
not exponential
The answer for this equation is 25
Answer:
x = 2
y = -8
Step-by-step explanation:
9x−2y=34 -------------------(I)
5x+2y=−6 -------------------(II)
Add equation (I) & (II) and so y will be eliminated and we could find the value of x.
(I) 9x - 2y = 34
(II) <u>5x + 2y = -6</u> {add}
14x = 28
x = 28/14
x = 2
Plug in x = 2 in equation (I)
9*2 - 2y = 34
18 - 2y = 34
-2y = 34 - 18
-2y = 16
y = 16/-2
y = -8
