Which is the equation of a hyperbola with directrices at x = ±2 and foci at (4, 0) and (−4, 0)? x squared over 8 minus y squared over 8 equals 1 x squared over 8 minus y squared over 16 equals 1 y squared over 8 minus x squared over 8 equals 1 y squared over 16 minus x squared over 8 equals 1

Plot the points (0,6), (3,15.8), and (9.5,0) using the graphing tool, and find the function

If y varies directly as x2 and y=6 when x=6, find the constant of variation.

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.
