Help me please Write a simplified equation to solve for X.

Using the equation, solve for x

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.)

Sole the equation 6n + 9 = -3n - 21 - 6 for n

Which is the standard form for this number? (2 x 10) + (5 x 1) + (8 x 1 10,000 )
