Answer:
Picture 1:
12x+1=109
12x=108
x=9
Picture 2:
2x-3=57
2x=60
x=30

2.4 minutes is 144 seconds. divide -216.12 by it to get altitude per second. This is 1.5 meters per second. Multiply this by 60 to get the rate per minute, totaling 90.05 meters per minute. Sorry if this explanation was long that was how I remember.
Well... to solve use rise over run... that is to find the slope,
now to find the y-intercept you look at what coordinate crosses the y-axis.
y= (what you got for the slope Ex. 1/2)x + (the y-intercept)
Figure it out and you got the answer with just a bit of help!!!
Hope this helps!
Exponential decay is a very common process especially when we are talking about radioactive materials. So, there is already a common formula for this type of behavior which is written below:
A = Pe^-rt
where
A is the amount left after time t
P is the initial amount at t=0
r is the rate
Substituting the values,
A = (780 g)(e^-0.163*16)
A = 57.5 g
