Jessica has been tracking the population of a town. The population was 8,230 last year and has been increasing by 1.25 times eac

h year. How can Jessica develop a function to model this?
f(x) = (8230 ⋅ 1.25)x where 1.25 is the rate of growth

f(x) = 8230(1.25)x where 1.25 is the rate of growth

f(x) = 1.25(8230)x where 8230 is the rate of growth

f(x) = 8230(x)1.25 where 8230 is the rate of growth

Initial population = 8230

The population is:
After 1 year, 8230(1.25)¹
After 2 years, 8230(1.25)²
 ...
After x years, 8230(1.25)ˣ

The population after x years is
f(x) = 8230 (1.25)ˣ

Answer:  8230(1.25)ˣ, where 1.25 is the rate of growth.
The second answer is correct.

What is an equation of the line that passes through the points (-4, 2) and<br> (-8,3)?
inn [45]

Answer:

y = --0.25x + 1

Step-by-step explanation:

In order to find the equation of a line, you must first find the slope of the line.

The equation to find slope is  \frac{y_2 - y_1}{x_2 - x_1}.

Plug in the given points:

(x2, y2) = (-8,3)

(x1, y1) = (-4,2)

(y2 - y1) / (x2 - x1) = (3-1)/ (-8 - -4) = (3-2) / (-8 + 4) = 1/-4 = -0.25

Next, you solve for the y-intercept using one of the two coordinates:

y = -0.25x + b

2 = -0.25(-4) + b

2 = 1 + b

b = 2 - 1 = 1

y = -0.25x + 1
