Hello, Marymack!
We know that in a geometric sequence defined by
and
, the sum can be calculated the following way:
Answer:
Option C. linear: slope = -5, y-intercept = 50
Step-by-step explanation:
Let
b ----> is the automatic decrease on the gift card balance
m ----> is the number of months beyond two years
we know that
The equation of the line into slope intercept form is equal to
where
m is the slope
b is the y-intercept
In this problem the linear equation that represent this situation is
---> equation of the line into slope intercept form
so
The slope is -5
The y-intercept is 50
Answer:
It is 2
Step-by-step explanation:you add 1 plus 1
