Answer:
The answer is A. Axis of symmetry: x = –1; Vertex: (–1, 0); f(x) = –x2 – 2x – 1 or C. Axis of symmetry: x = –1; Vertex: (–1, –1); f(x) = –x2 – 2x – 1

Answer:
4+4=8
Step-by-step explanation:
Piece(1)=36+9= 45 in
45 in > 44 in
so, piece(1)>piece(2)
-2x+3=5x-4
3+4=5x+2x
7=7x
x=1
y=5x-4=5*1-4=5-1=1
(1,1)
The answer is B.98
180-122=58
58+24=82
180-82=98
Hope it helped
