Answer:
<h2>y = 6,000x + 80,000</h2>Step-by-step explanation:
Givens
- The population increased 6000 people per year. (This is the constant ratio of change, because it offers information about the relation between variables).
- In 1980, the population was 80,000. (This is the initial condition, the population at the beginning of the period, that's why is the y-intercept of the function).
We know that the linear form has an explicit form
Where is the constant ratio of change and
is the y-intercept. Replacing given values, we have
Therefore, the right answer is B.

Given that
Function;
We have to determine
The graph of the function f(x).
According to the question
The logarithmic function is the inverse of the exponential function.
Function;
To plot the graph of the given function we have to find the asymptotes;
Vertical asymptote at x =0
The point at x= 1 is,
The point at x= 3 is,
The point at x= 9 is,
Hence, the points for the given function are (1,0) (3,1) and (9,2).

Answer:
Marion bought 6 frog lures and 8 lizard fishing lures.
Step-by-step explanation:
Let represent frog lures and
represent lizard lures.
The total packages Marion bought is
If she bought frog lures in packages of 4 and lizard lures in packages of 6 for a total of 72 lures, then
We make the subject in equation 1 and put it into equation 2 to get;
We put equation 3 into equation 2 to get;
We expand the bracket to get;
We put into equation 3 to get;
Therefore Marion bought 6 frog lures and 8 lizard fishing lures.
