Answer:
so
slope is calculated this way:

let's calculate y init by:
3 = -3×2 + b
b = 9
so equation is:
y=-3x+9
Adding a negative number is the same as subtracting a positive number. So 2315.5 - 3166.75 = -851.25
100,000 would be the answer
Answer:
The sum of first five term of GP is 19607.
Step-by-step explanation:
We are given the following in the question:
A geometric progression with 7 as the first term and 7 as the common ration.


Sum of n terms in a geometric progression:

For sum of five terms, we put n= 5, a = 7, r = 7

The sum of first five term of GP is 19607.
Verification:

Thus, the sum is equal to product of 2801 and 7.
