Hi
6% increase is multiply by 1,06
done 40 times
so : 250* 1,06^40 = 2571 ,
Answer:
the system of equation has infinite solution
Step-by-step explanation:
, ![25x_1 + 5x_2 = 0](https://tex.z-dn.net/?f=25x_1%20%2B%205x_2%20%3D%200)
Solve the first equation for x_2
Subtract 5x1 on both sides
![5x_1 + x_2 = 0](https://tex.z-dn.net/?f=5x_1%20%2B%20x_2%20%3D%200)
![x_2 =-5x_1](https://tex.z-dn.net/?f=x_2%20%3D-5x_1)
Now substitute -5x1 on second equation
![25x_1 + 5x_2 = 0](https://tex.z-dn.net/?f=25x_1%20%2B%205x_2%20%3D%200)
![25x_1 + 5(-5x_1)= 0](https://tex.z-dn.net/?f=25x_1%20%2B%205%28-5x_1%29%3D%200)
![25x_1-25x_1= 0](https://tex.z-dn.net/?f=25x_1-25x_1%3D%200)
0=0
So the system of equation has infinite solution
