Instruction active writing the contrapositive given the statement "if a line is horizontal, then it has slope equal to zero," what is its contrapositive? if a line is horizontal, then it has zero slope. if a line has zero slope, then it is a horizontal line. if a line is not horizontal, then it does not have zero slope if a line does not have zero slope, then it is not a horizontal

b) the dogs need to shift their focus to human scent.

step-by-step explanation:

i think the answer is d im not sure

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.
