3 = v
2 = b
3h+2h is less than or equal 30
v+b is greater than or equal to 12
so it is the last set of inequalities
It’s -4 because when you take 4 out of 8 then you still have another 4 to take away to you go into the negatives and have the answer -4
5+4=9
9+4=13
13+4=19

The quadratic model is f(x) = -5x^2 + 200.
f(x) = 50 meters
x = time in seconds
50 = -5x^2 + 200
5x^2 = 150 // Here, divide both side by 5
x^2 = 30
x =

seconds
Or approximately 5.48 seconds
