What is (-1) to the 39 power

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.)

Solve the following inequalities and show the solution on a number line. 2x+3< 3(4x+5)
