Use the graphing calculator tool to plot the residual points

(1.0.86), (2, -0.25), (3, -1.66), (4, -2.34), (5, 4.1)

Does the residual plot show that the line of best fit is
appropriate for the data?

- Yes, the points have no pattern.
- Yes, the points are evenly distributed about the x-
axis.
- No, the points are in a linear pattern
- No, the points are in a curved pattern

How do the graphs of y = 1/x and y=5/x+6 compare?

The tuition costs, c, for a local community college are modeled by c(h) = 250 + 200h, where h represents the number of credit hours taken. the local state university has tuition costs, s, modeled by the function s(h) = 300 + 180h. how many credit hours will a student have to take for the two tuition costs to be equal? round the answer to the nearest tenth of an hour.

Which situation can be modeled by the inequality 5 + 10w ≥ 45? a. you start with $5 and save $10 a week until you have at least $45. b. you start with 5 baseball cards and purchase 10 cards every week until you have at most 45 cards. c. you start with 5 water bottles and purchases cases of 10 water bottles each until you have a total of 45 water bottles. d. you spend $5 plus $10 per week until you have less than $45.
