Answer:
<h2>y = 2x - 3</h2>
Step-by-step explanation:
y = (slope)x + (y-intercept)
Let's say David's age right now is x years
x + 6 = 2(x - 7)
x + 6 = 2x - 14
x = 20
Therefor David is 20 years old
It is a cuz to be a function the x (domain) can only have one y (range) in d it is the number 2 in the 2nd and fourth set of ordered pairs in c it is 3 the first one and the 3rd in b it is -1 its the first and the last one
hope i helped you if u dont mind can i have brainlest <span />
Since the cross section is uniform, the depth of the water is irrelevant. The rate of change of height is the rate of change of volume divided by the area.
dh/dt = (dV/dt)/(π·r²)
= (9 ft³/min)/(π·(3 ft)²)
= 1/π ft/min ≈ 0.3813 ft/min
