Step-by-step explanation:
6x - 3x^2 + 2x^2 -2x = 5x^2 + 15x
4x -x^2 = 5x^2 + 15x
-11x - 6x^2 = 0
-6x^2 - 11x = 0
use the quadratic formula
(-b±√(b²-4ac))/(2a)
Step-by-step explanation:
To find how many people lived outside of the country we subtract:
3.853 × 
- 1.114 × 
= 3.7146 ×
To find the percentage of people living inside the country, we divide:
percent or 2.89%. Which is extremely small.
Answer:
y = 4x; there are an infinite number of solutions
Step-by-step explanation:
Both equations describe the same relation between x and y. The system is "dependent", so has an infinite number of solutions. For any value of x, the solution is ...
(x, y) = (x, 4x)
