Answer:
B. 5
Step-by-step explanation:
We have been given that R varies directly with S. When S is 16, R is 80. We are asked to find constant of variation.
We know that two directly proportional quantities are in form
, where,
k = Constant of variation.
Upon substituting our given values, we will get:




Therefore, the constant of variation is 5 and option B is the correct choice.
The answer to this question is 100% B: y=2x+7 I hope this helped you! :)
Answer:
(-5,2), (-5,4), and (-1,1)
Step-by-step explanation:
Answer:
Step-by-step explanation:
B is correct: We Divide it (the coefficient b) by 2 and square the result.
20/100 * X = 8
X = 8*100/20
X=40
