Which statement regarding sets a, b, and c is true? if ac b and b = c, then acc if a + b and b c, then a#c if a e b and b c, then aec if a cb and b sa, then a - b = a

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
