Answer:
The answer to your question is 2 or (2, 0)
Step-by-step explanation:
Data
slope = m = 4
y-intercept = -8
Process
1.- Write the equation of the line in the slope y-intercept
y = mx + b
In this equation:
m = slope
b = y-intercept
-Substitution
y = 4x - 8
2.- To find the x-intercept, consider that y = 0 and solve for x.
0 = 4x - 8
4x = 8
x = 8/4
x = 2 or (2, 0)
0.00100037227 will be your correct answer.
Formula for growth:
y = initial • (percent growth + 1)^time/frequency of growth
So, since initial population is 382
Percent growth is 0.007
The time is 30 years
And it goes it by .07% every 1 year,
y = 382 • (1.007)^30/1
y= 470.9203732 people
Since we can’t have 0.9 of a person, the population after 30 years will be 470 people.
