What is the solution of the system?

Serjik [45]

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)

-68x=884

-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

15, 11, 7, 3, -1, ... explicit formula and recursive formula

monitta

Recursive formula is: $a_n = a_{n-1} -4$

Explicit formula is: $a_n = 19-4n$

Step-by-step explanation:

Given sequence is:

15,11,7,3,-1

Here

$a_1 = 15\\a_2 = 11\\a_3 = 7$

First of all, we have to find the common difference

Common difference is the difference between consecutive terms of an arithmetic sequence

So,

$d = a_2-a_1 = 11-15 = -4\\d = a_3-a_2 = 7-11 = -4$

Recursive Formula:

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:

$a_n = a_{n-1} + d$

Putting the value of d

$a_n = a_{n-1} -4$

Explicit Formula:

The explicit formula is given by:

$a_n = a_1 + (n-1)d$

Putting the first term and common difference

$a_n = 15 + (n-1)(-4)\\a_n = 15 -4n+4\\a_n = 19-4n$

Hence,

Recursive formula is: $a_n = a_{n-1} -4$

Explicit formula is: $a_n = 19-4n$
