-3x+2 < 8
-2 -2
-3 /-3x <6/-3
x >-2
So x>-2
Exponential change can be modeled by:
N = N(0) x λⁿ; where λ is the rate of change. It is greater than 1 when there is growth and less than 1 when there is decay. n is the number of time periods passed.
λ is 1 + 0.083 = 1.083
N(0) is the initial value of 750
n is 2050 - 2005 = 45 years
N = 750 x (1.083)⁴⁵
= 27,000 fish
The answers are C and B.
Answer A has infinite solutions, and D has no solutions
divide 486 by 9 = 54
it would take about 54 minutes
