Use the example above and determine the fraction of total interest paid. after the seventh month of a 12-month loan: the numerator is: {(n + 11) + (n + 10) + (n + 9) + (n + 8) + (n + 7) + (n + 6) + (n + 5)} = , and the denominator is: {(n) + (n + 1) + + (n + 11)} = . therefore, the fraction is numerator/denominator (to the nearest tenth) = %.

answer:

the fraction is : 63/78 = 0.81.

step-by-step explanation:

numerator is: {(n + 11) + (n + 10) + (n + 9) + (n + 8) + (n + 7) + (n + 6) + (n + 5)}

where n is the month so, n=1 adding all n and all values we get:

7n+56 = 7(1) + 56 = 63

denominator is: {(n) + (n + 1) + + (n + 11)}

n= 1

12n + 66 = 12(1) + 66 = 78

so, the fraction is : 63/78 = 0.81.

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:
