Answer:
Answer is -6
Step-by-step explanation:
We can say that f(x) = 3x - 12
According to the question we have:
f(2) = 3x - 12
This means that x = 2
To solve this we substitute 2 in place of x
-2 + 2
2 people
8 have both that means that of the 11 people that have cats 3 have only cats and of the 13 that have dogs 5 only have dogs therefore 2 people don't have four-legged animals at home
