9. Lanie has decided to add strength training to her exercise program. Her trainer suggests that she add weight lifting for 5 minutes during her routine for the first week. Each week
thereafter, she is to increase the weight lifting time by 2 minutes. How many minutes
will she be devoting to weight lifting in week 10?

476 minutes

Step-by-step explanation:

for one week she did 5 minutes per day which makes it 35 minutes in the first week. the next nine weeks she has to do it for 7 minutes every day. you will have to multiply 63x7. after nine weeks of doing it for 7 minutes per day, she will have exercised for 441 minutes. after the whole ten weeks, including the first week, she will have exercise for 476 minutes.

I think this is right... just did the math rn

you need to add a picture

a.)the line for function b is steeper
