Kaitlyn is walking on a treadmill at a constant pace for 36 minutes. She has programmed the treadmill for a 2-mile walk. The display counts backward to show the distance
remaining.
Enter and graph the equation that gives the distance f(x) left in miles as a function of the
number x of minutes she has been walking. Then, find and compete the interpretation of
the x- and y-intercepts.
The equation is f(x) =

Which equation results from adding the equations in this system? x+6y=9 and -x+2y=-15

Which scenarios are most effectively explored by conducting an experiment? there is more than one correct answer. select all that apply. researchers want to study the effectiveness of a particular drug for treating migraines. they want to know which dosage of the drug yields the best results with the least side effects. to ensure fair results, the researchers want to ensure that participants and dosage administrators do not know which dosage participants receive. a teacher wants to plan a class fieldtrip and quickly determine where students prefer to go for the class fieldtrip. a car mechanic wants to know which of two engine brands makes better-performing engines. he wants to test the engines in identical situations and rate their performance in a way that can be fairly measured. a chemist studies the properties of a metal compound. she wants to know how the sample size of the metal affects its ability to conduct electricity. she wants to conduct the research in a controlled environment to minimize bias. a realty company wants to know the average income of its clients. the company wants to gather data income from current clients.

For the functions f(x) = -922 – 2x and g(x) = -32? + 6x – 9, find (f - g)(x) and (f - ).
