Ok so 8:12 can be 8 to 12, or 8\12
do that help?
1.
easy
(x,y)
minus 4 from the first number and if you get the same 2nd number, it is a solution
2-6=-4, nope
6-2=4 yep
-2-6=-8, nope
-6-2=-8, nope
he answer is B or (6,2)
1.
multiply first by 5 and get 2nd number
(x,y)
-2*5=-10, nope, trying to get 10
-5*5=-25, nope trying to get 25
-3*5=-15, ope trying to get 15
-2*5=-10, yep
answer is (-2,10) or D
She cannot fit 4 into 2 since it is a smaller number.
Answer:
Step-by-step explanation:
Given
--- time (years)
--- amount
--- rate of interest
Required
The last 10 payments (x)
First, calculate the end of year 1 payment
Amount at end of year 1
Rewrite as:
Next, calculate the end of year 1 payment
Amount at end of year 2
Rewrite as:
We have been able to create a pattern:
So, the payment till the end of the 10th year is:
To calculate X (the last 10 payments), we make use of the following geometric series:
The amount to be paid is:
--- i.e. amount at the end of the 10th year * rate of 10 years
So, we have:
The geometric sum can be rewritten using the following formula:
In this case:
So, we have:
So, the equation becomes:
Solve for x
