Step-by-step explanation:
GIVEN: Auditoriums are often designed so that are fewer seats per row for rows closer to the stage. Suppose you are sitting in row 
in an auditorium and notice that there are 
seats in your row. It appears the row in front of you has 
seats and the row behind you has 
seats. Suppose this pattern continues throughout the auditorium.
TO FIND: a) How many seats are in the first row b) How many seats are in the 
row?
SOLUTION:
total seats in 
total seats in 
total seats in 
as it clearly form an A.P. with 
(a)
let total seat in first row be 
as total seats in 
total seats in first row are
(b)
total seats in be 
total seats in row are
Answer:
k(x) = |x - 4| - 2
Step-by-step explanation:
So we know that k(x) is shifted 4 untis to the right and 2 units down. In an absolute value function, the value you move to the left will be positive and the value you move to the right will be negative. Since we are moving to the right, our value will be negative.
When you shift the function up or down, you will either subtract or add that value out side the absolute value. Since we are shifting down 2 units, that means we will be subtracting by 2.
Best of Luck!
Let x = the total cost of gas, dollars.
Originally, each of the three friends was to pay x/3 dollars each.
Finally, with two more friends added, the cost became x/5 dollars each.
The savings for each of the original three friends is $11, therefore
x/3 - x/5 = 11
(2x)/15 = 11
x = (11*15)/2 = $82.50
Answer: The total cost of gas is $82.50
