7 0

Hello friend!

1/3(9x+12)=15

We move all terms to the left:

1/3(9x+12)-(15)=0

Domain of the equation: 3(9x+12)!=0

x∈R

We multiply all the terms by the denominator

-15*3(9x+12)+1=0

multiply elements

-45x(9+1=0

Identify each sequence as arithmetic or geometric. Explain your answer, and write an explicit formula for the

hammer [34]

Answer:

Arithmetic sequence

$a_n=\frac{1}{2}-n$ for $n\geq 1$

Step-by-step explanation:

We are given that a sequence

$-\frac{1}{2},-\frac{3}{2},-\frac{5}{2},-\frac{7}{2},...$

We have to identify the sequence as arithmetic or geometric and write an explicit formula .

$a_1=-\frac{1}{2}$

$a_2=-\frac{3}{2}$

$a_3=-\frac{5}{2}$

$a_4=-\frac{7}{2}$

$d_1=a_2-a_1=\frac{-3}{2}+\frac{1}{2}=-1$

$d_2=a_3-a_2=-\frac{5}{2}+\frac{3}{2}=-1$

$d_1=d_2=-1$

When the difference of consecutive terms is constant then the sequence is an arithmetic.

Hence, the sequence is an arithmetic.

$a_n=a+(n-1)d$

$a_n=-\frac{1}{2}+(n-1)(-1)=-\frac{1}{2}-n+1=\frac{1}{2}-n$ for $n\geq 1$

Evaluate 4log4(3,100)

alexdok [17]

Answer:

${ \tt{4 log_{4}(3100) }} \\ = { \tt{4 log_{4}(775 \times 4) }} \\ = { \tt{4 log_{4}(775) + 4 log_{4}(4) }} \\ = { \tt{4( (\frac{ log_{10}775 }{ log_{10}4 } ) +1)}} \\ = { \tt{4(4.8 + 1)}} \\ = { \tt{23.2}}$
