Question

Noah's cousin is exactly 7 years younger than Noah. Let M represent Noah's cousin's age in months and N represent Noah's age in years. 1. If Noah is 15 years old, how old is his cousin, in months? 2. When Noah's cousin is 132 months old, how old is Noah, in years? 3. Write a function that gives the age of Noah's cousin in months, as a function of Noah's age in years. 4. Write the inverse of the function you wrote. What are the input and the output of this inverse function?​

Answer 1

Answer:

1,if Noah is 15 his cousin is 8 or 96 months

2, and when Noah's cousin is 132 months or 11 years old Noah will be 18

3,n-[[7]12]=age of Noah's cousin

Step-by-step explanation:

1,15-7=8

1 part 2, 8*12=96

2,132/12=11

2 part 2,

11+7=18

3,n-[[7]12]=age of Noah's cousin

4,n+[7/12]

if n=18

18+[7/12]

or

18+0.5833=18.5833
