At the end of the third year the population of beetles will be 11,576beetles
<h3>Exponential equations</h3>
The standard form of an exponential function is given as:
y = ab^t
Given the following parameters
initial population 'a" = 10,000 beetles
Time = 3 years
rate b = 1.05
Substitute into the formula
y = 10,000(1.05)^3
y = 10,000(1.1576)
y = 11,576 beetles
Hence at the end of the third year the population of beetles will be 11,576beetles

The point-slope form:

m - slope
The formula of a slope:

We have the points (-2, 3) and (1, -3). Substitute:

The standard form: Ax + By = C. Convert:
<em>use distributive property</em>
<em>subtract 3 from both sides</em>
<em>add 2x to both sides</em>
