Please see pic, I'd solved in it.
Hello from MrBillDoesMath!
Answer:
Domain = { 5. 10. 15. 20}
Range = -3,-1,1,3}
.
Discussion:
The domain is the set of all "x" values, that is { 5. 10. 15. 20} and the range is (-3,-1,1,3}
. The arrows in the diagram show the mapping between the domain and the range. For examples, 5 -> 1 ( "x value 5 is mapped to y value 1"), 10 ->3, 15 ->-3, and 20 -> -2
Thank you,
MrB
C is the least that is beause it is .015 which is smaller than 0.15
Answer:
27 years
Step-by-step explanation:
Given that :
Town A:
Initial population = 14280
Rate = increase by 160 per year
Let t = time in years
Population is thus :
14280 + 160t - - - (1)
Town B:
Initial population = 24000
Rate = decrease by 200 per year
P = 24000 - 200t - - - (2)
Equate both equations :
14280 + 160t = 24000 - 200t
160t + 200t = 24000 - 14280
360t = 9720
t = 9720 / 360
t = 27
