Answer:
B. 6x - 12y + 10x
Step-by-step explanation:
A: expression equals 10x - 12y, doesn't equal step 2
B: expression equals 16x - 12y, is the same as step 2
C: expression equals 16x - 30y, doesn't equal step 2
D: expression equals 25x - 30y, doesn't equal step 2
I believe #7 would be 5:13, #8 to be 6:7, #9 to be 13:18, #10 to be 18:5.
I hope this helps.
Hmmm it would be kind of hard to graph as it will be a curved line but the middle of the line would be at (2,-7). Not (-2,-7).
And it will be curving upwards, meaning it will start by going down and end by going up.
Hope this helps some.

Answer:
14.7
Step-by-step explanation:
Perhaps your equation is ...
f(t) = N·e^(-0.2174t)
We want f(6) = 4, so ...
4 = N·e^(-0.2174·6) = N·e^-1.3044 ≈ 0.2713N
N = 4/0.2713 = 14.7 . . . . milligrams
The dose amount was about 14.7 mg.
