A = 49.0 rounded to 1 DP
b= 7.62 rounded to 2 DP
Find the minimum of a - b

a-b

49.0-7.62

41.38 right or wrong tell

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

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.
