Answer:
B. -1, 2, -4, 8
Step-by-step explanation:
The characteristic of a geometric sequence is that adjacent terms have a common ratio. Sequence B is the only one.
2/-1 = -4/2 = 8/-4 = the common ratio: -2
___
Ratios of adjacent terms are different for the other sequences.
Answer:
A. 
Step-by-step explanation:
Let
be the equation of the perpendicular line.
Two perpendicular lines have slopes with product equal to -1. The slope of the given line is
Hence,

is the slope of needed line.
This line passes through the point (-4,2), so its coordinates satisfy the equation:

Therefore, the equation of the line is

Answer:
8 * 7 = 3 * 18
Simplifying
8 * 7 = 3 * 18
Multiply 8 * 7
56 = 3 * 18
Multiply 3 * 18
56 = 54
Solving
56 = 54
Step-by-step explanation:
U put 35 on the side to make 5 like that’s. The opposite
