Question

Which of the following has no solution?

(x + 1 < -1) ∩ (x + 1 < 1)
(x + 1 ≤ 1) ∩ (x + 1 ≥ 1)
(x + 1 < 1) ∩ (x + 1 > 1)

Answer 1

solve the inequalities and see if the solutions intersect

for example take the first one

x + 1 < -1
x < -2

x + 1 < 1
x < 0


so do the solutions overlap?

Answer 2

if so then A has a solution

Answer 3

Yes! Thank you!

Answer 4

yea so its not A
Check out the other 2

Answer 5

looks like C
