Write an equation of a line that passes through the point (2, 3) and is parallel to the line y = 3 over 2x + 5.

Consider that lines b and c are parallel. what is the value of x? what is the measure of the smaller angle?

Parabolas y=−2x^2 and y=2x^2 +k intersect at points a and b that are in the third and the fourth quadrants respectively. find k if length of the segment ab is 5.
