What is -2-(9-10n) please help it could change my life. It would be very nice

1 answer:

6 0

Distribution property
a(b+c) = ab*ac

now, why does this matter

cause
-(9-10n) is equivalent to -1*(9-10n)

applying distribution property
-1*(9-10n) = -1*9 +-1-10n= -9 +10n

So can anyone help me with #1 and 2 and show work I have no idea what I’m doing

Neporo4naja [7]

Answer:

x = 44*2

x = 62*2

x = 108/2

x = 160/2

12x = 60*2

12x = 120

x = 120/12

5x = 50/2

5x = 25

x = 25/5

Find the explicit formula for the sequence? -1,4,-16,64......

Ede4ka [16]

The explicit formula for given sequence is: $a_n = -1 . (-4)^{n-1}$

Step-by-step explanation:

Given sequence is:

-1,4,-16,64.....

We can see that there is no same difference between consecutive terms so we will find common ratio to see if it is a geometric sequence.

Here

$a_1 = -1\\a_2 = 4\\a_3 = -16\\a_4 = 64\\r = \frac{a_2}{a_1} = \frac{4}{-1} = -4\\r = \frac{a_3}{a_2} = \frac{-16}{4} = -4$

The explicit formula for geometric sequence is:

$a_n = a_1r^{n-1}$

Putting the values of r and a1

$a_n = -1 . (-4)^{n-1}$

Hence

The explicit formula for given sequence is: $a_n = -1 . (-4)^{n-1}$
