Answer:
Step-by-step explanation:
In a geometric sequence, the consecutive terms differ by a common ratio,r. Considering the given sequence,
r = 6/- 2 = - 18/6 = - 3
Therefore, the sequence is geometric.
The formula for determining the nth term of a geometric progression is expressed as
Tn = ar^(n - 1)
Where
a represents the first term of the sequence.
r represents the common ratio.
n represents the number of terms.
From the information given,
a = - 2
r = - 3
The explicit formula is
Tn = - 2 × (- 3)^(n - 1)
To find the 8th term, T8,
T8 = - 2 × (- 3)^(8 - 1)
T8 = - 2 × (- 3)^7
T8 = - 2 × - 2187
T8 = 4374
Answer: there is almost no relationship between x and y.
Explanation:
The coefficient r tells how well the data fix into the model chosen.
A value r = 1 indicates a perfect positive linear relation.
A value r = - 1 indicates a perfect negative linear relation.
Intermediates values may be interpreted more or less in this way:
1) 0.7 < |r| < 0.7 => strong relation between the variables
2) |r| ≈ 0.5 moderate relation between the variables
3) |r| ≈ 0.3 poor relation between the variables
4) |r| ≈ 0 non-relation between the variables.
1 ton i think! i hope this helps
Since they are both equal to y, you can set -7x and x+8 equal to each other.
- 7x = x + 8 and solve for x then use what you got for x to solve for y
