Answer:
1. f(x)=x+7
2. f(x)=1.2x
Step-by-step explanation:
1. If f(x+5)=x+12, then substitute

Hence,

Now change t into x:

2. If f(x-5)=1.2x-6, then substitute

Hence,

Now change t into x:

Answer:
3, 230, 000, 000, 000
Explanations:
10^12 = 1, 000, 000, 000, 000,
So...
3.23 * 10^12 = 3, 230, 000, 000, 000
The sum of 12 and a number
(12 + n)
is no greater
< =
then the sum of twice the number and 8
(2n +(-8)) = (2n - 8)
so we have :
(12 + n) < = (2n - 8)
