Which equation has infinitely many solutions? A. 12.8+32x+10.2=32x2.6

B. 1/13(26x-169=1/12(-156+24x)

C. 2(3-2x)=-5x+7

D. 1/2x(3/2-2/3)+24=4/18

There is a line with slope 1/a going through the point (a, a²). find the equation of the line perpendicular to this line at this point. (don’t let this problem intimidate you! solve the problem as you would if i’d given you specific values. just use variables instead.)

What could explain what happened when the time was equal to 120 minutes

Someone me! if you’re smart you can solve this!
