Answer: $15*(x-3)^2*(x-5)$

Step-by-step explanation:

$\dfrac{x^2-y^2}{x^2-8x+15}\ and\ \dfrac{y^2}{15(x^2-6x+9)} \\\\\\x^2-8x+15=x^2-3x-5x+15=x(x-3)-5(x-3)=(x-3)(x-5)\\\\15(x^2-6x+9)=15*(x-3)^2\\\\LCM (x^2-8x+15,15(x^2-6x+9)\\\\=LCM((x-3)(x-5),15(x-3)^2)\\\\\boxed{=15*(x-3)^2*(x-5)}\\$

Complete the point-slope equation of the line through (-5,4) and (1,6). Use exact numbers.

BigorU [14]

ANSWER

$y - 6 = \frac{2}{7} (x - 1)$

EXPLANATION

The point-slope equation of a straight line is given by:

$y-y_1=m(x-x_1)$

Where m is the slope.

The line goes through (-5,4) and (1,6).

The slope of this line is,

$m = \frac{6 - 4}{1 - - 6}$

$m = \frac{2}{7}$

The point-slope equation is

$y - 6 = \frac{2}{7} (x - 1)$
