Let x equal the age, in human years, for a dog that is 2 years old or older. for each of your chosen breeds, write an expression to model its age in dog years. [hint: use (x - 2) in each expression.]

these are the dog years:
2yrs: 23 yrs old
3yrs: 27 yrs old
4yrs: 31 yrs old
5yrs: 35 yrs old

i'm having trouble with making an expression, !
