Parallel lines have same slope, so first isolate y to get the equation into y=mx+b form.
-2x+3y=2
3y = 2x + 2

Now plug the point (3,4) into y = 2x + b
4 = 2(3) + b
Solves for be
b = -2
So the new equation is y = 2x - 2
The quantity that is present after 2000 years will be A. 7.851 grams.
<h3>How to calculate the quantity?</h3>
From the information given, initially at t = 0, the quantity is 10 grams.
After 2000 years, the appropriate quantity will be:
Q(2000) = 10 (1/2) × (2000/5730)
Q(2000) = 7.851 grams.
In conclusion, the correct option is A.

Answer:
The right answer is: Option C: x+5
Step-by-step explanation:
Let m1 be the miles Lukas drove on Saturday and Let m2 be the miles he drove on Sunday

The difference can be found out by subtracting m2 from m1
minus sign will be distributed into the bracket and alike terms will be added or subtracted according to sign.

The difference of miles driven is: x+5
Hence,
The right answer is: Option C: x+5
