Answer:
15(x - 5)(x - 3)²
Step-by-step explanation:
factor both denominators and see what you need to do to make them equal...
(x² - y²)/[(x - 5)(x - 3)] y²/[15(x - 3)(x - 3)]
the first denominator has (x - 5)(x - 3)
the second denominator has 15(x - 3)(x - 3),
the least common denominator between them would be
15(x - 5)(x -3)(x - 3) or 15(x - 5)(x - 3)²
Y-intercept, it can be described as y-intercept form, or another way of writing it in mathematical form is y=mx+b, this can be used to draw polygons, find ortho-centers (very difficult), etc. m is the rise/run, rise over run, or 1/2. The rise and the run is the rate of change. b is the starting point or slope where it starts at, that is most of it!
The correct answer is the 5th option (one before the last one).
