The face of a clock is divided into 12 equal parts. the radius of the clock face is 6 inches. assume the hands of the clock will form a central angle. which statements about the clock are accurate? check all that apply. the central angle measure when one hand points at 2 and the other points at 4 is 60°. the circumference of the clock is about 19 in. with one hand at 5 and the other at 10, the minor arc formed by the hands is about 15.7 in. the minor arc measure when one hand points at 1 and the other hand points at 9 is 150°. the length of the minor arc between 11 and 2 is the same as the length of the minor arc between 7 and 10. a, c,e

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.
