Hi!

<h3>Let's solve this. </h3><h3>First, subtract the 2nd equation from the first.</h3>

-2x = -2y - 8

- -2x = -2y - 8

----------------------

<u>0 = 0</u>

<h2>Yes, it does, because any value you use for x and y will be the correct answer. </h2>

Hope this helps! :)

Write an equation for the nth term of the arithmetic sequence. Then find a10.
Misha Larkins [42]

Answer:

-3n

a10= -30

Step-by-step explanation:

the distance between -3 and -6 is 3.

if you multiply 3 by the 1st term, it's just 3, so the 3 needs to be a -3.

For a10, you plug in 10 into the equation which is -3n. and that is -30.

10. An arithmetic sequence has this recursive formula. What is the explicit formula?​
Mrrafil [7]

Answer:

a_{n}=45-3n

Step-by-step explanation:

Method 1:

Arithmetic sequence is in the form

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

d is the common difference, can be found by:

d=a_{n}-a_{n-1}=-3

Subtituting the a_{1} and d

You get:

a_{n}=42+(-3)(n-1)=45-3n

Method 2 (Mathematical induction):

Assume it is in form a_{n}=45-3n

Base step: a_{1} =45-3(1)=42

Inducive hypophesis: a_{n}=45-3n

GIven: a_{n+1} =a_{n}-3

a_{n+1}=45-3n-3=45-3(n+1)

Proved by mathematical induction

a_{n}=45-3n
