so the total amount lowered is 12 + 11 + 8 , which is a total elevation change of 31 feet
Answer: Option D) 6
Solution:
xy=k
What is the constant of variation: k=?
when x=-3 and y=-2
Replacing the knwon values in the given equation:
xy=k; x=-3, y=-2
(-3)(-2)=k
Multiplying the values:
6=k
k=6
Answer:
Algebraic, common difference = −9
Step-by-step explanation:
The first term of the series is 81, the second term is 72, the third term is 63 and the fourth term is 54.
So, the value of the terms decreases as the number of terms increases and this decrease in value is common and it is 9.
Therefore, the series is Algebraic series and the common difference is - 9. (Answer)
The answer is option B. Hope this helps:)
Answer:17/12
Step-by-step explanation:2/3 + 3/4 = 2 · 4/3 · 4 + 3 · 3/4 · 3 = 8/12 + 9/12
= 8 + 9/12= 17/12
