What is the solution set of {x | x < -3} ∩ {x | x > 5}? A. the empty set

B. all numbers except -3 and 5

C. all real numbers

D. the numbers between -3 and 5

2.
What is the solution set of {x | x < 2}U{x | x ≥ 2}?

A. all numbers less than -2 and greater than 2
B. all real numbers
C. the empty set
D. the numbers between -2 and 2

3.

Which of the following describes the graph of {x | 1 < x < 2}?

A. open circles on 1 and 2, line segment between
B. open circles on 1 and 2
C. open circles on 1 and 2, arrows pointing out
D. no solution

Step-by-step explanation:

#1

Intersection of the two given sets is the empty set as the sets cover two different intervals without common elements.

Correct choice is A

#2

Assume there is a union sign between sets.

The union of the two sets is both of them.

Correct choice is B

#3

Both the points are excluded, so both ends are open circles and the graph covers the interval between them.

Correct choice is A

1) A

2) B

3)A

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
