Answer:
A
Step-by-step explanation:
x^2 + 7x+ 10. factors out to (x - 2)(x + 5)
I get:
24 = 3x-12
add 12 to both sides
36 = 3x
divide each side by 3 and you will get 12
So basically an arithmetic sequence has a common difference, a number which is either added or subtracted at a constant rate (only that number). A geometric sequence is the ratio between two numbers, meaning they are either multiplied or divided by the same number. The sequence would be neither if it follows none of these patterns. So by this logic:
14. Arithmetic, 15. Geometric, 16. Neither, 17. Geometric
To solve this problem, start by plugging in your given n value.
This results in:
k = 100 - 4(60)
Next, simplify the parentheses by multiplying the -4 and the 60 together.
This leaves you with:
k = 100 - 240
To simplify for k, subtract 240 from 100 to get:
k = -140
So your final answer is k = -140 when n = 60

Answer:
No
Step-by-step explanation:
The initial balance at the beginning of the year is not zero, so the balance is not proportional to the time since the beginning of the year.
__
A proportional relationship always starts at zero when the independent variable is zero.
