How do I slove this eqaution, and whats the answer?<br> -3(n+6)+10=-9

Sauron [17]

Answer:

$n = \frac{1}{3}$

Step-by-step explanation:

Apply the distributed property, so it now looks like this: -3n + -18 + 10 = -9
Combine like terms: -3n + -8 = -9
Simplify: -3n - 8 = -9
Add 8 to each side, so it now looks like this: -3n = -1
Divide each side by -3 to cancel out the -3 next to n. It should now look like this: n = 1/3

I hope this helps!

2. Find the common difference and the recursive formula. a. 22, 19, 16, 13, …

Musya8 [376]

Answer:

The common difference d is d = -3

The recursive formula is: $\mathbf{a_n=a_{n-1}-3}$

Step-by-step explanation:

We need to find the common difference and the recursive formula.

a. 22, 19, 16, 13, …

First we will find common difference

The formula of arithmetic sequence is: $a_n=a_1+(n-1)d$

where a_n is nth term, a_1 is 1st term and d is the difference

Looking at the sequence we get: a_1=22, a_2=19

Using these values we can find d, the common difference

$a_n=a_1+(n-1)d\\put\:n=2, a_2=19, a_1=22\\19=22+(2-1)d\\19=22+d\\d=19-22\\d=-3$

So, the common difference d is d = -3

Now, we will find the recursive formula:

The recursive formula is of type: $a_n=a_{n-1}+d$

We have found common difference d = -3

So, the recursive formula will be:

$a_n=a_{n-1}+d\\a_n=a_{n-1}+(-3)\\a_n=a_{n-1}-3$

The recursive formula is: $\mathbf{a_n=a_{n-1}-3}$
