Answer:
0.2
Step-by-step explanation:
you move 9x to make 6x-1=2-9x
then move the 1 to make 6x=3-9x
so this means that 15x=3
so x=0.2
The pattern that is summed may be written as
S = 1 - 3 + 9 - 27 + . . .
= (-3)^0 + (-3)^1 + (-3)^2 + (3)^3 + . . .
The n-th term in the sum is (-3)^n, for n = 0,1,2,3, . . .
The sum may be written with summation notation as
So for this, we will be forming a proportion. In this case, our proportion is going to be: . From here we can solve for x.
Firstly, cross-multiply:
Next, divide both sides by 6, and your answer will be (rounded to the whole hour)
Step-by-step explanation:
1 is your answer its law of trig identises
Answer:
x and y = 0
the question looks weird and almost wrong because when you subtract the equations, you are left with nothing
Step-by-step explanation:
Multiply the top equation by 3 to make the -x a -3x instead.
Then do the top equation - the bottom equation
At this point you should be left with x
