-x(3+4)
If you distribute it to all the numbers the simplest form would be -3x-4x
For the equation
take the
from both sides:
Find x:

Answer: correct choice is D
The equation of the asymptote is 
Explanation:
The given equation is 
We need to determine the horizontal asymptote of the equation.
The given equation is of the exponential function of the form
and has a horizontal asymptote 
Hence, from the above equation, the value of k is 1.
Therefore, we have,

Thus, the horizontal asymptote is 
Therefore, the asymptote of the equation is 
615.44 rounded to the nearest tenth is 615.4
