Answer:
4
Step-by-step explanation:
y = -(x + 1)² + 1
Shift 1 unit to the right:
y = -(x + 1 − 1)² + 1
y = -x² + 1
Shift 5 units down:
y = -x² + 1 − 5
y = -x² − 4
Rotate 180° about the vertex:
y = -(-x²) − 4
y = x² − 4
Find the zeros:
0 = x² − 4
x² = 4
x = -2 or 2
Therefore, a = -2 and b = 2, so b−a = 4.

Step-by-step explanation:
8x+15 = 2x+39
8x =2x+24
6x = 24
x = 24/6 = 4
angle 4 = 2(4) +39 = 8+39 = 47
angle 6 = angle 4
angle 6 = 47 degrees
Answer:
an = 63(-1/3)^(n-1)
Step-by-step explanation:
This is a geometric sequence with first term 63 and common ratio -1/3.
The equation for the nth term is
an = 63(-1/3)^(n-1).
