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

Answer:
2
Step-by-step explanation:
y2 - y1 / x2 - x1
-2 - 4 / -1 - (-4)
-2 - 4 / -1 + 4
-6 / 3
2
4 less (-4) 5 times a number (5n) is (=) 11 (11)
-4+5n=11
add 4 to both sides
4-4+5n=11+4
0+5n=15
5n=15
divide both sides by 5
5n/5=15/5
1n=3
n=3
the number is 3
