Which graph represents the piecewise function
i attached the problem

x+y=90

x=30-y=x

step-by-step explanation:

if you understand you will get the answer

36

step-by-step explanation:

8

step-by-step explanation:

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
