It costs $1.20 per person and $3.75 per hour to rent a meeting room at the library. Let x represent the number of people and y represent the number of hours. If 3xpeople rented the room for 2yhours, write an expression to represent the total cost of the rental?

1.2(3x)+3.75(2y)

Step-by-step explanation:

multiply 1.2 by what you know for number of people

multiply 3.75 by what you know for number of hours

tube or goog would be a great resource to with that question

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
