L S = sin x/( 1 + cos x) * ( 1 - cos x ) / ( 1 - cos x ) =
= sin x ( 1 - cos x ) / ( 1 - cos² x ) =
= ( sin x - sin x cos x ) / sin² x =
= sin x / sin² x - ( sin x cos x ) / sin² x =
= 1 / sin x - cos x / sin x = csc x - cot x = RS
Therefore: LS = RS
Answer:
A. y -9 = 2(x -1)
Step-by-step explanation:
The point-slope form of the equation of a line is ...
y -k = m(x -h) . . . . . line with slope m through point (h, k)
You are given m=2 and (h, k) = (1, 9). Putting these values into the form gives ...
y -9 = 2(x -1)
<span>Simplifying
4x2y + 12xy2 + 9y3
Reorder the terms:
12xy2 + 4x2y + 9y3
Factor out the Greatest Common Factor (GCF), 'y'.
y(12xy + 4x2 + 9y2)
Factor a trinomial.
y((2x + 3y)(2x + 3y))
Final result:
y(2x + 3y)(2x + 3y) if its not sorry

There are three steps
1 rearrange the equation so "y" is on the left and everything else is on the right
2 plot the "y=" line (make it a solid line for y< or y> and a dashed line for y< or y>)
3 shade above the line for a "greater than" (y> or y>) line under that or below the line for a less than (y< or y< line under it)
