The right ans is D.I am 100%sure.
if my ans was gelpful u can follow me.
Answer:f(x)=4x+1=9
=> 4x=9-1
=> 4x=8
=>x=2
Step-by-step explanation:
Answer:
1)
=0.3571428571 2) Terminating
Step-by-step explanation:
1st. To answer this question let's divide with long division algorithm 5 and -14.

5 (dividend) : -14 (divisor) 
Long division (check below)
With the same two numbers -14 and 5 we can write in a Long Division
5) -14
<u> - 2.8</u>
5) -14
10
40
So 
2nd. Both are terminating ones for they have finite quantities of numbers. -2.8 and 0.3571428571, as we can see that these are rational numbers for they can be written as a/b, and b≠ 0.
