Answer:
x = 2
Step-by-step explanation:
The relevant rule of logarithms is ...
log(a/b) = log(a) -log(b)
This lets us combine the logs on the left to get ...
log((6 +7x)/(3x -2)) = log(5)
Taking anti-logs gives ...
(6 +7x)/(3x -2) = 5
6 +7x = 5(3x -2) . . . . . multiply by (3x -2)
7x +6 = 15x -10 . . . . . eliminate parentheses
8x = 16 . . . . . . . . . . . add 10-7x to both sides
x = 2 . . . . . . . . . . . . . divide by 8
The solution is x = 2.
_____
The graph shows the left side of the equation is equal to the right side for x=2.
If you observe carefully, you can see that the graph is crossing x-axis at the points 1 and 9. This means x = 1 and x = 9 are the roots of the polynomials and x - 1 and x - 9 are thus the factors of the polynomial.
We can express the polynomial as the product of its factors. So the above polynomial can be expressed as (x - 1)(x - 9)
Thus, the answer to the question is option D
