Answer:
The explicit formula for a given geometric sequence is of the form

Step-by-step explanation:
Given sequence is 
Let
To find the common ratio r:



Therefore r=-3



Therefore r=-3
Therefore common ratio is -3
Therefore given sequence is geometric sequence.
The explicit formula for a geometric sequence is
, where common ratio is r.
From given sequence we are having r=-3
Therefore the explicit formula for a given geometric sequence is of the form 


Answer: See below
Step-by-step explanation:
(f+g)(x) is another way for saying f(x)+g(x). Since we know f(x) and g(x), we can add them together.
-5x-4+(-3x-2) [distribute the 1 to (-3x-2)]
-5x-4-3x-2 [combine like terms]
-8x-6
(f+g)(x) is -8x-6. You can also factor this.

Answer:
R 694.4
Explanation:
simple interest =
→
→ R 134.4
where p refers to principal, r refers to rate, t refers to time.
total money:
invested money + simple interest
R 134.4 + R 560 → R 694.4
Answer:
39
Work:
(x+5)/2=22
We will reverse this equation.
We will start by moving the 2 through inverse operations.
22x2=44
Now we have the equation
x+5=44
We will subtract 5
44-5=39
x=39
the unknown variable equals 39

Answer:
The first one, first check the slope (3/2) because it's positive it illuminates the second and forth, then the slope only matches the first one from there. meaning it must be the first
