Answer:
ok
Step-by-step explanation:
I'd suggest you begin by subtracting 4 / (x-4) from both sides. Doing that would leave you with 1 / (x-4) - 2 / (x+2) = 0.
LCD is (x-4)(x+2). Mult. all three terms by (x-4)(x+2). The resulting equation is
x+2 - 2(x-4) = 0. Then x+2 = 2x - 8 => x = 10
Subst. 10 for x in the original equation to verify that 10 is indeed a solution.
Answer:
There is no additive inverse only a multiplication because 1/2 is division so you have to do multiplication. But the answer to that is 2.
Since we are dealing with a volume problem (3 dimensions) when you increase the radius by a factor of 2, you increase the volume by a factor of 2^3 or 8
So, the larger sphere has a volume 8 times greater than the smaller sphere.
The differences are
2000 119
2010 176
2020 154
2030 -436
Due to the small size data set, it would not be appropriate to predict future years unless some proven method applicable to this case is used.
