Isolate z by itself:
To simplify variables with powers, subtract the smaller power from the bigger power:
The exponent will be
-3.
The values of is 2 and r are -1 of the geometric series and it can be determined by using geometric summation operation.
Given that,
The geometric series is,
2 – 2 + 2 – 2 + 2
We have to determine
What are the values of a1 and r of the geometric series?
According to the question,
<h2>
Geometric series;</h2>
2 – 2 + 2 – 2 + 2
The geometric series is the first term of the geometric sequence and r is the common ratio of the geometric series.
The first term of the given geometric series is 2.
And the common difference in the given geometric series is,
Where is the first term of the geometric sequence and is the second term of the geometric sequence.
Then,
The common difference in the given geometric series is,
The common ratio in the given geometric series is -1.
Hence, the values of is 2 and r is -1 of the geometric series

Answer:
The statement is false
Step-by-step explanation:
The lines mean the absolute value of whatever is inside of them. Therefore you can never get a negative number equal to it.
Answer:
y = 1.20x
Step-by-step explanation
Let's call x the length of the beams in feet
Llamemps f (x) at the price of beams.
The function represented by this model is the line y = 1.20x
Where 1.20 is constant price per foot.
If the price per foot is $ 1.20, then, the price of each beam according to its size is:
6 * 1.20 = $ 7.2
8 * 1.20 = $ 9.6
10 * 1.20 = $ 12
12 * 1.20 = $ 14.4
Then we have the following points, which will constitute the domain and rank for the function:
(6, 7.2)
(8, 9.6)
(10, 12)
(12, 14.4)
