Add  9  to each side:       2x      < 16

Divide each side by  2 :    x       < 8 .

shusha [124]

Answer:

n = -6

Step-by-step explanation:

-3n + 9 = 27 (Given)

-3n + 9 - 9 = 27 - 9 (Subtraction Property of Equality)

-3n = 18 (Simplify)

\frac{-3n}{-3} = \frac{18}{-3} (Division Property of Equality)

n = -6 (Simplify)

Determine the recursive function that defines the sequence.
Strike441 [17]
<h2>Answer:</h2>

Option: C is the correct answer.

    C.   f(1)=4\\\\f(n)=5\cdot f(n-1)\ ;\ n\geq 2  

<h2>Step-by-step explanation:</h2>

Recursive Formula--

It is the formula which is used to represent the nth term of a sequence in terms of (n-1)th term of the sequence.

Here we are given a table of values by:

            n            f(n)

            1              4

            2             20

            3             100  

i.e. when n=1 we have:

f(1)=4

Also,

f(2)=20\\\\i.e.\\\\f(2)=5\cdot 4\\\\i.e.\\\\f(2)=5\cdot f(1)

Also,

f(3)=100\\\\i.e.\\\\f(3)=5\cdot 20\\\\i.e.\\\\f(3)=5\cdot f(2)

Hence, the recursive formula is:

f(n)=5\cdot f(n-1)\ for\ n\geq 2
