I dont know exactly what your asking but x=-y-2
Answer:
The American population was 20% of the British population.
Step-by-step explanation:
Let us call
the american population,
the British population before the migration, and
the population that migrated from America to Britannia.
Now, the population
that migrated was 20% of the american population:
,
and the same population
increase the British population by 4%:
![x+B = 1.04B \\\\ (2). \:\:x = 0.04B.](https://tex.z-dn.net/?f=x%2BB%20%3D%201.04B%20%5C%5C%5C%5C%20%282%29.%20%5C%3A%5C%3Ax%20%3D%200.04B.)
Combining equation (1) and (2) we get:
![0.2A = 0.04B](https://tex.z-dn.net/?f=0.2A%20%3D%200.04B)
![A = \dfrac{0.04B}{0.2}](https://tex.z-dn.net/?f=A%20%3D%20%5Cdfrac%7B0.04B%7D%7B0.2%7D)
![\boxed{A = 0.2B}](https://tex.z-dn.net/?f=%5Cboxed%7BA%20%3D%200.2B%7D)
Thus, the American population was 20% of the British population.
Step-by-step explanation:
As seen from the graph, f(x) and g(x) intersect each other when x = 3.
Hence, f(3) = g(3).
