Answer:
The units of the average growth rate is number of accidents per day.
Step-by-step explanation:
We are given the following in the question:
The independent variable is the day of the year.
The function is the cumulative number of accidents since the first of the year at a certain dangerous intersection.
Average growth represents the rate at which the dependent variable changes as the independent variable changes.
Independent variable: day of the year
Dependent variable: cumulative number of accidents
Thus, the growth rate will have units
Thus, the units of the average growth rate is number of accidents per day.

Answer:
y = - x + 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m =
with (x₁, y₁ ) = (0, 3) and (x₂, y₂ ) = (4, 0) ← 2 points on the line
m = = -
The line crosses the y- axis at (0, 3 ) ⇒ c = 3
y = - x + 3 ← equation of line
The equation which represent total amount of income he earns from selling book is,
Since, Selling price of one novel is n dollars
So, selling price of b books is,
Since, he receives 9% commission on each book sale.
So, total commission he receives on selling of b books is,
And also he received a bonus of $50,000 to sign the contract to write the book,
So, total amount of income he earns is represented by A,
