Answer:
a(n) = 9.5 + 2(n - 1)
Step-by-step explanation:
Observe that each new term is obtained by adding 2 to the previous term. Thus, the common difference is 2 and the first term is 9.5.
Then a(n) = 9.5 + 2(n - 1)
The value of x is -3.5
Because dividing both sides by -2.4 is going to get you a value of -3.5. And a negative divided by a negative is a positive. :D
Answer:
a) $4,960
b) 8% per annum
c) $120
Step-by-step explanation:
a) 4000 + 960 = $4960
b) 960 ÷ 3 = 320 per year
320/4000 × 100 = 8%
c) 1% more per year:
1% of 4000 = 40
3 years: 120
So $120 more
Since he lost 5 every month, it should be that the slope is -5, not 5, he is not gaining 5 every month
yint is 100 and slope is -5 would be correct
b=-5m+100
b=number of blocks he has after m months
