Answer:
m = 3
Step-by-step explanation:
BD is angle bisector of <ADE
so
<BDE= <ADB
6m - 3 = 15
6m = 18
m = 3
(-9x-6y=-54) +(8x+6y=50)= -x=-4; x=4
3(4)+2y=18
12+2y=18
2y=6 ; y=3

It’s probably too late but
Point M is now at (7,1)
Since we can't have a 0 in the denominator,
Also, in the graph ...you can see that the function approaches x=5 but never actually reaches it.
∴The value of x that don't lie in the domain of the function is
5
