It’s 80,610 if you really mean the tens place.
If you mean the one tenths place then it’s 80,607.2
Answer:
I'd say that a is 6 2/3 units long
Step-by-step explanation:
Answer:
(-13,-4)
Step-by-step explanation:
4x-8y=-20
9x+113=y
Substitute in y for 9x+113
4x-8y=-20
Substitute
4x-8(9x+113)=-20
Simplify
4x-72x-904=-20
Simplify
-68x-904=-20
Additive Prop. of Equality
-68x-904+904=-20+904
Simplify
-68x=884
Isolate the variable(x)
<u>-68x</u>=<u>884</u>
-68x -68x
Simplify
x=-13
Solve for y
9x+113=y
9(-13)+113=y
-117+113=y
-4=y
Check
4x-8y=-20
4(-13)-8(-4)=-20
-52+32=-20
-20=-20
9x+113=y
9(-13)+113=-4
-117+113=-4
-4=-4
Recursive formula is: 
Explicit formula is: 
Step-by-step explanation:
Given sequence is:
15,11,7,3,-1
Here

First of all, we have to find the common difference
Common difference is the difference between consecutive terms of an arithmetic sequence
So,

<u>Recursive Formula:</u>
A recursive formula is used to find the next term of an arithmetic sequence using previous term and common difference
General form of recursive formula for a given common difference d is:

Putting the value of d

<u>Explicit Formula:</u>
The explicit formula is given by:

Putting the first term and common difference

Hence,
Recursive formula is: 
Explicit formula is:
