Find an equation of the line that bisects the acute angles formed by the lines with equations 2x+y-5=0 and 3x-2y+6=0
Neko [114]
The solving for the first one should be like this 

2x+y-5/sqrt 2^2 1^2=2x+y-5/sqrt5
And the next part 3x-2y+6/sqrt 3^2 -2^2=3x-2y+6/sqrt13

After these manipulations just multiply them 

(2sqrt13-3sqrt5)x+(sqrt13+2sqrt5) y-5sqrt13-6sqrt5=0 

And finally you need to square and simplify for the completed answer

F(x)=5/x-1<br> g(x)=4-2x<br> Calculate fg(x)
Leno4ka [110]

Answer:

Step-by-step explanation:

define function fg(x) :

Fg(x)  = f(g(x))

         = \frac{5}{x} (4-2x)-1

         = \frac{20}{x} - \frac{10x}{x} - 1

         = 20 - 10x -1

         = 20 - 1 - 10x

         = 19 - 10x

Kite K L M N is shown. The lengths of sides L M and M N are congruent. The lengths of L K and K N are congruent. Angle K is 99 d
Tresset [83]

Answer

\angle \ LMN=49\textdegree

Step-by-step explanation:

The diagonals of kite KLMN meet at 90°

Since, LK and KN are congruent,\angle KLM and\angle KNM form a set of opposite congruent angles. Congruent angles are equal.

All interior angles of a kite add up to 180°, therefore:-

\angle LMN=360\textdegree - 2\times106\textdegree-99\textdegree\\=49\textdegree
