F(x) = -x^2 + 6x + 6
where f(x) represents the height, in feet, of the water from the fountain at different times x, in seconds
rate of change of a distance is speed
at x=5, distance = 11
at x=2, distance = 14
so average rate of change = (14-11)/(5-2) = 1
so ans is D
Y=mx+b
b=y intercept
the current one is y=-2
6 units up is -2+6=4
new one is 4
-5m-20-80+50m=0
45m=100
m= 20/9
61 = 3b + 7
3b + 7 = 61
3b = 61 - 7
3b = 54
b = 54/3
b = 18.
There are 6.4 Kilometers in 4 miles
