Jimmy graphs the equations y= 10x + 2 and y= 2/3x - 17. He concludes that all equations starting with “y =“ are linear fictions because the points on each of these graphs lie on a straight fit line. Select all equations that show Jimmy’s conclusions is incorrect.

A:y= 20- 4x
B:y= x^2 - 1
C:y= 5x^3 + 9
D:y= 2x (x - 3)
E:y = 15

In triangle △abc, ∠abc=90°, bh is an altitude. find the missing lengths. ah=4 and hc=1, find bh.

Tom is the deli manager at a grocery store. he needs to schedule employee to staff the deli department for no more that 260 person-hours per week. tom has one part-time employee who works 20 person-hours per week. each full-time employee works 40 person-hours per week. write and inequality to determine n, the number of full-time employees tom may schedule, so that his employees work on more than 260 person-hours per week. graph the solution set to this inequality.
