Of the 100 oil paintings at the museum, 28 were portraits. What percentage of the oil paintings on display were portraits?

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.

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.

60 for the first and 130 for the second

step-by-step explanation:

the correct answer would be d because the slope is -2/2=1 and the y intercept is at 2 so that is the correction equation
