Answer:
B
Step-by-step explanation:
And arithmetic sequence is a sequence in which the difference between each of the numbers are constant.
It is not A, because the difference between 3 and 9 is positive 6, and the difference between 9 and 81 is positive 72.
It is not C, because the difference between 4 and 1 is -3, and the difference between 1 and 4 is positive 3.
It is not D, because the difference between 2 and -2 is -4, and the difference between -2 and 2 is positive 4.
And it is B because the numbers maintain a constant difference between each other, which is -3.
Answer:
The solve of this equation is X = 4,06
Step-by-step explanation:
To solve this formula:
2 ( X² - 16) = 1
You must use the distributive law of multiplication, thus:
2X² - (16×2) = 1
2X² - 32 = 1
2X² = 1 + 32
X² = 33/2
X² = 16,5
X = √16,5
X ≈ 4,06
Thus, the solution of this equation is:
<em>X ≈ 4,06</em>

Answer:
17.6
Step-by-step explanation:
Formula= sumfx÷sumf
sumfx= 63×0+34×0+27×1+13×2=53
sumfx=0+0+1+2=3
53÷3= 17.6
final answer =17.6

The coordinates of X would be X'(-4, -5).
The equation would be P(x,y) -> P'(-x, y) so you would make the x-coordinate a negative number and keep the y-coordinate the same.
