Are you asking what the answer is because you are not asking us anything. I would really like to help you out but I need to know what the question is first.
To reflect a function across the y-axis you have to change

So, the function becomes

Midpoint formula: (x1+x2/2 , y1+y2/2)
So, (-1+3/2 , 9+8/2)
-2/2 = -1 17/2 = 8.5
Answer: (-1,8.5)
Answer:
A -(27x + 7)
B -(15x + 8 )
C -9(2x + 1 )
Step-by-step explanation:
-1/2 (30x + 16) = -15x-8
Hence, the values of x, y and z are as follows:
x=10
y=5
z=2
Further explanation:
When two triangles are congruent, then their respective sides will also be congruent or equal
As it is given that
ΔABC≅ΔDFE
Which means that
EF = BC
ED=AC
FD=AB
Now,

Hence, the values of x, y and z are as follows:
x=10
y=5
z=2
