Describe the possible echelon forms of the standard matrix for a linear transformation t where t: set of real numbers is onto.

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.

The functions below show the amount of money bella and sweet t had saved after earning money for doing chores. which description best compares the two functions?
