Y=-7x-15
The formula to write the equation is
Y=mx+b
m=slope
m=-7
b=y intercept
b=-15
Answer:
127.5
Step-by-step explanation:
The given series is 26 + 24.5 + 23 + 21.5 + ... - 17.5
The first term of this series is a=26
The common difference is d=24.5-26=-1.5
The last term of the series is -17.5
The nth term is given by:




n=30
The sum of the series:



The function
is an exponential with base greater than 1. So, its range is
, with 0 being the horizontal asymptote as
.
If you multiply the function by
, the range remains the same.
If you reflect it over the x-axis, you're changing the sign of the function. So, the new range is
