Which statements are true about circle q? check all that apply. the ratio of the measure of central angle pqr to the measure of the entire circle is . the area of the shaded sector is 4 units2. the area of the shaded sector depends on the length of the radius. the area of the shaded sector depends on the area of the circle. the ratio of the area of the shaded sector to the area of the circle is equal to the ratio of the length of the arc to the area of the circle.

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.
