1. A patient going into surgery has been injected with 250 milligrams of Ativan, a drug commonly given to ease anxiety. The amount of the drug in the body decreases at a rate of 33% per hour. Create a function that models the number of milligrams of Ativan in the patient's system 1 hours after being injected with the drug. 2. Using the equation you created, algebraically, determine to the nearest hour, when the patient will have 20 milligrams of Ativan left in their system.

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

there are 25 people coming to the party

step-by-step explanation:

the text says that there will be 22 children at this party, 1 teacher, and 2 parents. so if you add them all together (22+1+2) it will equal 25. (=25)
