Step-by-step explanation:
2x+3=x+x+3
add the X's on the right side together.
2x+3=2x+3
subtract 2x from both sides
3=3
subtract 3 from both sides
0=0
the statement is true for any value of x
Answer is 2a.
(1) Rephrase the expression as (15-13)a

Rounding rules of rounding up if the next place is 5-9, or rounding down if the next place is 0-4.
Answer:
Step-by-step explanation:
First of all, your question is very clear. Excluding 0 is a needed restriction.
f(1) = 3*1 + 1 = 3 + 1 = 4
f(2) =3*2 + 1 = 6 + 1 = 7
f(3) = 3*3 + 1 = 9 + 1 = 10
f(4) = 4*3 + 1 = 12 + 1 = 13
4,7,10,13
Notice that you are just adding 3 to the previous term.
