Answer:

x = -2

Step-by-step explanation:

$3[- x + (2x + 1)] = x - 1$

$= > 3[ - x + 2x + 1 ] = x - 1$

$= > 3[x + 1] = x - 1$

$= > 3x + 3 = x - 1$

$= > 3x - x = - 1 - 3$

$= > 2x = - 4$

$= > x = \frac{ - 4}{2} = - 2$

Answer:

Circumference: 12.56 yd
Area: 12.56 yd²

Step-by-step explanation:

The circumference is given by ...

C = πd

C = (3.14)(4 yd) = 12.56 yd

The area is given in terms of diameter by ...

A = (π/4)d²

A = (3.14/4)(4 yd)² = 12.56 yd²

Which recursive formula can be used to generate the sequence shown, where f(1) = 5 and n > 1?

Degger [83]

The recursive formula $a_n = a_{n-1}-6$ can be used to generate the shown sequence

Step-by-step explanation:

Recursive formula is the formula that is used to generate the next term of a sequence using previous term.

The general form of arithmetic sequence's recursive formula is:

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

Given

5,-1,-7,-13,-19

Here

$a_1 = 5\\a_2 = -1\\a_3 = -7$

First of all we have to find the common difference of the sequence.

So,

$d = a_2 -a_1 = -1-5 = -6\\d = a_3-a_2 = -7+1 = -6$

Putting the value of d in the general recursive formula

$a_n = a_{n-1}-6$

Hence,

The recursive formula $a_n = a_{n-1}-6$ can be used to generate the shown sequence
