First, notice that (a + 1/a)2 = 42 = 16. But also, (a + 1/a)2 = a2 + 2a(1/a) + 1/a2 = a2 + 2 + 1/a2 = a2 + 1/a2 + 2
So a2 + 1/a2 + 2 = 16, so a2 + 1/a2 = 14.
Now, do that again...
(a2 + 1/a2)2 = 142 = 196, but also (a2 + 1/a2)2 = a4 + 2(a2)(1/a2) + 1/a4 = a4 + 2 + 1/a4 = a4 + 1/a4 + 2
So a4 + 1/a4 + 2 = 196, so a4 + 1/a4 = 194
You can see the pattern... E.g., a8 + 1/a8 = 1942 - 2, etc.

Answer:

Step-by-step explanation:
The equation of the line is y = ( 4/3 )x + 2.
What is an equation of a line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
Given that the equation is parallel the line y = ( 4 / 3 )x + 8 and passes through the point ( -6 , -6 ).
The general equation of the line is
y = mx + c
The slope of the required line will be the same as the slope of the line parallel to the required line.
m = ( 4 / 3 )
The equation of the line will be written:-
y = mx + c
y = ( 4 / 3 )x + c
-6 = ( 4 / 3 ) x -6 + c
c = 2
y = ( 4/3 )x + 2
Therefore, the equation of the line is y = ( 4/3 )x + 2.

Answer:
x = - 20
Step-by-step explanation:
12x = -8(10 - x)
12x = -80 + 8x
12x - 8x = -80
4x = -80
x = -80/4 = -20

what tis -2(x-6) + 7= 35
. Im am very need of help.
ten points
You weren't clear with your question, but I am assuming you want to solve for the variable "x."
-2(x - 6) + 7 = 35
-2x + 12 + 7 = 35; distribute the -2
-2x + 19 = 35
-2x = 16; isolate the x variable (the variable you want to solve)
x = -8; divide by -2 to isolate the x variable
Answer:
[tex]x=-8[/tex]
Step-by-step explanation:
1) Distribute
[tex]-2(x-6)+7=35\\-2x+12+7=35[/tex]
2) Add the numbers
[tex]-2x+12+7=35\\-2x+19=35[/tex]
3) Subtract 19 from both sides of the equation
[tex]-2x+19=35\\-2x+19-19=35-19[/tex]
4) Simplify
A. Subtract the numbers
[tex]-2x+19-19=35-19\\-2x=35-19[/tex]
B. Subtract the numbers
[tex]-2x=35-19\\-2x=16[/tex]
5) Divide both sides of the equation by the same term
[tex]-2x=16 \\\frac{-2x}{-2} =\frac{16}{-2}[/tex]
6) Simplify
A. Cancel terms that are in both the numerator and denominator
[tex]\frac{-2x}{-2} =\frac{16}{-2}[/tex]
B. Divide the numbers
[tex]x=-8[/tex]
