Answer:
y-6=-1(x-2) hope this helps
Step-by-step explanation:
4x+10y=-13...you have to add the variables that are the same and then subtract the 13 from 0
This exponential growth/decay (in this case decay because r<1) of the form:
f=ir^t, f=final value, i=initial value, r=common ratio or "rate", t=time.
Since the population decreases by 4.5% each year the common ratio is:
r=(100-4.5)/100=0.955 so we can say
P(t)=8500(0.955^t)
....
7000=8500(0.955^t)
14/17=(955/1000)^t taking the natural log of both sides
ln(14/17)=t ln(955/1000)
t=ln(14/17)/ln(955/1000)
t≈4.22 years (to nearest hundredth of a year)
Since t is the years since 2010, the population will fall to 7000 in the year (2010+4.22=2014.22, more than four years will have elapsed) 2015.
Answer: 576 inches or 48 feet
Step-by-step explanation:
set up a proportion where 
so you get drawingAB = 24 in
actualAB = 18 feet = 18 * 12 in = 216 in
drawing perimeter = 64 in
so plug these in to get
rearrange to get 
and solve to get 576 inches or 576/12 = 48 feet
