Answer:
- 270 tickets were sold
- not needed: books per player, tickets per book
Step-by-step explanation:
To find the number of tickets sold, the total revenue needs to be divided by the revenue per ticket:
(total revenue)/(revenue/ticket) = total tickets
$810/$3 = 270 . . . total tickets
__
None of the other numbers in the problem are needed: books per player (1), tickets per book (10).
Answer:

Step-by-step explanation:
step 1
Determine the slope of the dashed line
The formula to calculate the slope between two points is equal to

we have
(-3,1) and (0,3)
substitute


step 2
Find the equation of the dashed line in slope intercept form

we have

---> given problem
substitute

step 3
Find the equation of the inequality
we know that
Is a dashed line and everything to the left of the line is shaded
so

see the attached figure to better understand the problem
(5x^3 + 4)(25x^6 - 20x3 +16) remember factoring the cubes?
