The first one is c because if you put it at negative 1/8 then it is 0-1/8 or 1/8 away from zero
second one is 
the
reciprocal is the number that when multiiplied by the number you are
trying to find the reciprocal of, you get +1 so the number you have is 
2/7 so 
2/7 times x=+1
multiply both sdies by 7/2 to clear fraction
x=+7/2
the reciprocal is +7/2 or +3 and 1/2 which is D

(m + 12) / 9m = 5 / 9
cross multiply
(5)(9m) = 9(m + 12)
45m = 9m + 108
45m - 9m = 108
36m = 108
m = 108/36
m = 3 <==
        
             
        
        
        
Answer:

Answer:
   $5599.20
Step-by-step explanation:
The quarterly interest rate for the first two years was ...
   7%/4 = 0.0175
So, the multiplier each quarter for those 8 quarters was 1+0.0175 = 1.0175. At the end of the first 8 quarters, the account value had been multiplied by ...
   1.0175^8
For the next 8 quarters, the quarterly interest rate was 10%/4 = 0.025. So at the end of those 8 quarters, the balance had been multiplied by ...
   1.025^8
Then the balance at the end of 4 years was ...
   $4000(1.0175^8)(1.025^8) ≈ $5599.20
The balance was $5599.20.
