Answer: D) x ≥ -6
Step-by-step explanation:
It is greater than or equal to negative six because the circle is black, and not white with a white outline. The reason it's greater than is because it's going to the right, and going into greater numbers.
Hope this helps. HAVE A BLESSED AND WONDERFUL DAY! As well as a great Valentines Day! :-)

I'm partial to solving with generating functions. Let

Multiply both sides of the recurrence by
and sum over all
.

Shift the indices and factor out powers of
as needed so that each series starts at the same index and power of
.

Now we can write each series in terms of the generating function
. Pull out the first few terms so that each series starts at the same index
.

Solve for
:

Splitting into partial fractions gives

which we can write as geometric series,


which tells us

# # #
Just to illustrate another method you could consider, you can write the second recurrence in matrix form as

By substitution, you can show that

or

Then solving the recurrence is a matter of diagonalizing the coefficient matrix, raising to the power of
, then multiplying by the column vector containing the initial values. The solution itself would be the entry in the first row of the resulting matrix.
Answer:
four hundred and forty two
A parallelogram has 4 sides.
So, we divide 72, the meters of the parallelogram. = 18
Now, the length is 4 more, so we add. 18+4=22
The length is 22.
Now, both lengths are 22, so double is 44; subtract 44 from 72. 72-44=28
In conclusion, we divided 28 by 2 to get the width of both sides.28/2=14
The width is 14.
Answer:
80%
Step-by-step explanation:
So, if x movies are thought to be very good out of a total of y movies,
Then the required ratio is = x/y
= 44/ 55
=4/ 5
=0.80
=80/100
So if a total of 100 movies watched, 80 of them are thought to be very good.
Thus the required answer is 80%.
