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, please help!

Verified Answer :

The expression is 4x + 19 because it goes up in 4 (27-23 etc) however it doesn't start on 4 it starts on 23 so you have to add 19 because 4+19=23

Answer = 4x + 19
