The equation that represents this description is h = 20c + 60 because hours (h) is our dependent variable and cost (c) is our independent variable. Hours (h) is our dependent variable because it depends on how many hours Mr. Z tutors the students. The slope of the function is 20 because that is how much Mr. Z charges to start off. What was this student's mistake? What is the correct equation that represents the description above?

c= 20h + 60

Step-by-step explanation:

The correct dependent variable for this equation is "c" cost of Mr Z's tutoring. The independent variable is "h" hours of tutoring. This is because the independent variable h hours should determine the cost of tutoring c. Therefore the equation can be interpreted: if there are h hours of tutoring which cost 20 per hour, total cost is equal c. Also slope of the equation is 20, coefficient of h.

how am i supposed to answer

step-by-step explanation:

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3
