<span>Answer:
Since X is the midpoint, you know WX=XY and VX=XZ (given to you in the problem statement)
When you draw your line segments, label the five points W,X,Y,V and Z
Now also draw line segments WV and ZY.
You now have two triangles.
The angle zxy = wxv since opposite angles are equal.
Given the above, you now have 2 triangles that are congruent using side-angle-side
Since the two triangles are congruent, then the sides opposite the angle x (WV and ZY) must be equal.</span>
Answer:
f^(-1)(x) = 3x/(2-x)
Step-by-step explanation:
f(x) = 2x/(x+3)
f(x)*(x+3)=2x
x(2-f(x))=3f(x)
x=3f(x)/(2-f(x))
f^(-1)(x) = 3x/(2-x)
Sin(8x)cos(x) - cos(8x)sin(x)
identity being used: -cos(s)sin(t) + cos(t)sin(s) = sin(s-t)
sin(8x)cos(x) - cos(8x)sin(x) --> simplified = sin(8x-x)
sin(8x-x) is simplified to --> sin (7x)
sin(8x)cos(x) - cos(8x)sin(x) = sin(7x)
