Answer:
10/3
Step-by-step explanation:
|x+3|=4x-7
So |-(x+3)|=|x+3|
We are going to try out two cases:
-(x+3)=4x-7                              and    x+3=4x-7
-x-3=4x-7                                               3=3x-7
  -3=5x-7                                               10=3x
   4=5x                                                   x=10/3
   x=4/5
We are going to test out both because we could something that isn't actually a solution, this is called extraneous. 
First thing I'm going to check is 4x-7 for it being positive.
4(4/5)-7=20/5-7=-15/5=-3 so 4/5 will not work because absolute value result can't be negative 
4(10/3)-7=40/3-7=19/3 which is positive 
checking |x+3| to see if is 19/3 for x=10/3 we see that is so that is the answer

Answer:
f(n) = 2 + 5n. This is an arithmetic sequence.
Step-by-step explanation:
 f(1) = 7
f(2) = 7 + 5
f(3) = 7 + 5 + 5 = 7 +10
f(4) = 7 + 5 + 5 + 5 = 7 + 15
In general,
f(n) = 7 + 5(n -1 )
         = 7 + 5n - 5
         = 2 + 5n
We have the sequence 7, 12, 17, 22, 27 …
This is an arithmetic sequence, because it is a sequence of numbers in which the <em>common difference</em> between consecutive terms is 5.
