For what value of x does 3^2x=9^3x-4
2 answers:
ANSWER
The value of x for which
is
EXPLANATION
The given equation is
This is an indicial equation or an exponential equation in x.
We can see that, this time, the variable is in the numerator.
So we need to express both sides of the equation to the same base to obtain,
Since the base are the same, we can now equate the exponents to get,
When we divide both sides of the equation by 2, we obtain,
We now group like terms to obtain,
We simplify the left hand side to get,
We finally divide through by negative 2 to obtain,
Therefore the correct answer is B.

Answer:
Follows are the solution to the given question:
Step-by-step explanation:
They can count the days of the year 1 to 365. The random project consists of drawing a sample of n objects from D where elements are n people's birth in a group but instead, D = {1,....365}. And then there's the issue.
This because the list of future birthdays of n people was its test point; therefore m points will be in the sequence so each point contains 365 distinct outcomes. The probability function P for \Omega is that any event is likely to happen in 365 days.
if x is between 1 and 365 as well as the occurrence is just all similarly possible
In point i:
That somebody mentions their birthday throughout the party
Guess I was born on day b. Therefore the consequence of "x is in A" is "b is now in the series of x," which is to say, b = bk for some amount k approximately 1 and n.
In point ii:
Any 2 persons share the same birthday at this party". A result x is in B" means which "two of entries in x are same." This means that perhaps the outcome x is in B if or only if bj = bk is in B of two numbers j, and k of 1, of two. , no, n.
In point iii:
Many three students share the same birthday with both the party. The consequence is x at the level of C only when bj = bk = bl at three (different) indices, j, k, l, 1. , no, n.
