Answer:
Option C is correct.
Bobby has $300 in the yearbook fund and earns $13.50 for each yearbook sold.
Step-by-step explanation:
Slope intercept form: An equation of line is given by:
......[1] where m is the slope and b is the y-intercept
Given the linear equation: 
Here, x represents the yearbook sold.
On comparing with the equation [1] we have;
m = $13.50
b =300
therefore, the best scenario best matches the linear relationship is:
Bobby has $300 in the yearbook fund and earns $13.50 for each yearbook sold.
Answer:
It would be distributive property.
Answer:
The bacterial culture loses
of its size every 7 seconds.
Step-by-step explanation:
The relationship between the elapsed time t, in seconds, and the number of bacteria, N(t), in the petri dish is modeled by the function:

Since the growth factor is less than 1, it is a decay equation.

Observe that the time t is divided by 7.
This is the period.
We can therefore say that the bacterial culture loses
of its size every 7 seconds.
Answer:
g(7) = 16
Step-by-step explanation:
When evaluating piecewise-defined functions, the first step is to determine which domain the value of the independent variable falls into. Then the associated function is evaluated in the usual way.
__
For x=7, the applicable domain is (2, ∞). This means the applicable function is ...
g(x) = (x +1)(x -5)
For x=7, this is ...
g(7) = (7 +1)(7 -5) = (8)(2)
g(7) = 16
