What is the answer to the equation 5+2(x-1)=12
S_A_V [24]
5+2(x-1)=12 \\ \\ 2 ( x - 1) = 12 - 5 \ / \ subtract \ 5 \ from \ each \ side \\ \\ 2(x - 1) = 7 \ / \ simplify \\ \\ x - 1 =  \frac{7}{2} \ / \ divide \ each \ side \ by \ 2 \\ \\ x =  \frac{7}{2}  + 1 \ / \ add \ 1 \ to \ each \ side \\ \\ x =  \frac{9}{2} \ / \ simplify \\ \\

So, the answer to this problem is x = 9/2 or x = 4.5.

Determine if each sequence is arithmetic, geometric, or neither.
Len [333]

9514 1404 393

Answer:

  • geometric
  • arithmetic
  • neither (Fibonacci sequence)

Step-by-step explanation:

If ratios are the same, it is geometric:

  8/4 = 16/8 = ... = 2

If differences are the same, it is arithmetic:

  -4-(-8) = 0 -(-4) = ... = 4

If neither is the case, it is neither:

  3-2 ≠ 5 -3

  3/2 ≠ 5/3

In this last sequence we see that differences equal the previous term. This is characteristic of the Fibonacci sequence, which sees wide use in Nature, and has a relationship to the Golden Ratio. (The ratios of successive terms approach the golden ratio (1+√5)/2 ≈ 1.618.)
