Melissa wants to buy a new hair dryer. She considers five models and assigns them belief ratings from 1= very poor to 10= very good and importance ratings from 10= most important to 1=least important. She sets a mental cutoff of 5 in order for the model to be selected. According to the conjunctive rule, which of the following models would she select?

Look at this system of equations. -3x + 3y = 12 y = x + 4 the solution set of this system is best explained by which of these statements? a) the graphs of the equations are the same line because the equations have the same slope and the same y-intercept. the system has infinitely many solutions. b) the graphs of the equations are parallel lines because they have the same slope but different y-intercepts. the system has no solution. c) the graphs of the equations are lines that intersect at one point because the equations have the same slope but different y-intercepts. the system has exactly one solution. d) the graphs of the equations are lines that intersect at one point because the equations have the same slope and the same y-intercept. the system has exactly one solution.
