^3 square root 54 + 3 ^3 square root 2x if x ≠ 0?

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.)

It says factor each expression 49x-28?

15 there is a line that includes the point 0,10 and has a slope of 7/4. what is it’s equation in slope intercept form
