Answer:
2x -3y =1 and 3x-2y= 4 has
Step-by-step explanation:
The pair of linear equations 2x-3y=1 and 3x-2y=4 has one unique solution. , then it has a unique solution other wise not. Since , , it means the pair of linear equations has only one unique solution. Hence, the pair of linear equations 2x-3y=1 and 3x-2y=4 has only one unique solution.
a1/a2= 2/3
b1/b2= 3/-2 (-) cancle so it remains
c1 / c2 = 1/4
a1/a2 = b1/b2 not equal to c1/c2 as no solution
Answer:
40
Step-by-step explanation:
so next year her money would be 6% more so:
5000 + (0.6 * 5000) = (1.06) * 5000
So each year she'll have : (1.06)*(last year's money)
So we can say after n years she will have :
((1.06)^n) * 5000
So:
5000((1.06)^n)=50000
n is 39.5
So around 40
