The correct answer would be A less than 1/2 inche
Answer:
6:14 and 9:21
Step-by-step explanation:
Answer:
-1, -2
Step-by-step explanation:
Since multiplication by 0 will result in 0, any value of x resulting in 0
(-1+1)(-1+2)=0
0x1=0
(-2+1)(-2+2)=0
-1x0=0
Let x = number of years between 1990 and 2000.
Rainbow smelt:
Initial population = 227
Average yearly rate of change = -19.76
The linear function that models the population is
y₁ = 227 - 19.76x
Bloater fish
Initial population = 1052
Average yearly rate of change = -92.57
The linear function that models the population is
y₂ = 1052 - 92.57x
When the two populations are equal, then y₁ = y₂.
That is
227 - 19.76x = 1052 - 92.57x
(92.57 - 19.76)x = 1052 - 227
72.81x = 825
x = 11.33 years
= 11 years, 0.33*12 months
= 11 years, 4 months
Add x to 1990 to obtain the year April 2011.
Answer:
x = 11.33 years.
This occurs in April 2001.
