Answer: the lines are not parallel.
Explanation: if you isolate the x in 3x^2-4y=-1, the equation is y=3/4x^2+1/4
So, they are not parallel because the slope is not the same.
        
             
        
        
        
Answer:
 8·549516
Step-by-step explanation:
To round the number given to 6 decimal place, we will follow the steps below;
First count six digits after the decimal point
Then after the six digit number take the next number and see if it below 5 then this means you will be rounding down, so you will leave your six digit after the decimal points the way they are and discard the other digits after the the six digits, but if the digit number right after the sixth digit is 5 and above, then you will be rounding up, you will add one to your sixth digit and then discard the digits after the sixth digits.
That is;
In the number given: 8.54951607694
The sixth digit after the decimal point is 6, the number that comes after it is zero, so we will leave the 6 the way it is and discard the other digits after 6
8.54951607694  ≈  8·549516  to 6 decimal place
