Multi-Part Seats in a concert hall are arranged in the pattern shown. Row 1 a. The numbers of seats in the rows from an arithmetic Row 2 sequence. Write a rule for the arithmetic sequence. Row 3 Row 4 b. How many seats are in Row 15? C. Each ticket costs $ 40.If every seat in the first 10 rows is filled, what is the total revenue from those seats? d. An extra chair is added to each row. Write the new rule for the arithmetic sequence and find the new total revenue from the first 10 rows.

step-by-step explanation:

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)

c. 1,233 miles
