3. suppose that g- (v,) is a graph. a matching is a subset of edges mce, satisfying the following two properties v ethere is at least one e em such that r is an endpoint of e v ethere is at most one e e m such that x is an endpoint of e. for the complete graph k (with 6 vertices) prove that the number of such matchings is 15.

Which of these triangle pairs can be mapped to each other using two reflections?

Select the correct answer from each drop-down menu. the length of a rectangle is 5 inches more than its width. the area of the rectangle is 50 square inches. the quadratic equation that represents this situation is the length of the rectangle is inches.

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.
