Which number line represents the solution set for the inequality -1/2 > 4

Which linear equations have an infinite number of solutions? check all that apply.  (x  –  3/7)  =  2/7(3/2x  –  9/14)8(x  +  2)  =  5x  –  1412.3x  –  18  =  3(–6  +  4.1x)(6x  +  10)  =  7(x  –  2)4.2x  –  3.5  =  2.1 (5x  +  8)

Click on the graphic until you find the right quotient. (36xa - 30xb) ÷ (-6x2)

What number should be added to both sides of the equation to complete this square? x^2-10x=7
