−10x + 1 + 7x = 37
combine like terms
-3x + 1 = 37
subtract 1 from both sides
-3x = 36
divide both sides by (-3)
x = - 12
Answer
x = - 12
Answer:
Yes, and it is already in descending order
Answer: f(n+1) = 3 f(n)
Step-by-step explanation:
- A recursive formula is used to determine each term of a sequence using preceding term or terms.
Given sequence : 2.5, 7.5, 22.5, 67.5, 202.5,...
Here,
Common ratio = 3
Let f(n) be a term in this sequence then the next term will be f(n+1) = 3 f(n), where n is a natural number .
Required recursive formula : f(n+1) = 3 f(n)
It could exist at either 15 or at -25. Both of these numbers are 20 away and distance is often measured in absolute terms.
So, to solve this, you just plop those x and y values into the equation. So:
3(8) -2(-5)= 6
24- (-10) =6
34=6
34=/=6
Since these two are not equal, the ordered pair <em />is not a solution.
