A refrigeration unit requires 4.6 pounds of refrigerant. Using a metric scale, you determine that there are 2.3 kilograms of refrigerant remaining in the charging cylinder. You know that one kilogram is the same as 2.205 pounds. How many pounds of refrigerant are in the cylinder? Round your answer to the nearest tenth of a pound.

                      4.0                                            Step-by-step explanation:

72 is the answer to this problem

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
