A pipe is leaking in the school bathroom. It has leaked 3 gallons of water in 6 hours.
COP=

COP [Constant of Proportionality or k] = ½

Step-by-step explanation:

y = kx.

y = dependent variable [vertical].

x = independent variable [horizontal].

y in this case is the gallons and x in this case is the hours.

Therefore

#gallons = 1/2 #hours

y = 1/2x

k = 1/2

This is because at a rate,

the pipe leaks at 1/2 or 0.5 gallons per hour.

$8

step-by-step explanation:

it is pretty much backwards.

you take the 4x2 multiply that, and that is = $8

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
