M=[(y2-y1)/(x2-x1)]
Sub in your points,
m=[(6)-(6)]/(4)-(-3)]
m=(0/7)
Which means that the slope is 0!
We'll say beginning amount is 100
Ending Amount = Beginning Amount / 2^n where n is the number of half-lives
100 hours mean six and 2/3 half-lives will elapse
Ending Amount = 100/2^(6.666666)
Ending Amount = 100 /

So if we started with 100 grams after 100 hours (or 6.6666666 half-lives) we would only have <span>

grams remaining.

Answer:Its D, just took the test.
Step-by-step explanation:
If we let x and y represent the prices of adult and child tickets, respectively, then we can write two equations based on the daily sales.
8x +5y = 108
x +14y = 67
A graphing calculator shows the solution of these equations to be
(x, y) = (11, 4)
The price of an adult ticket is $11.
The price of a child ticket is $4.
