Question

Solve (x - 2 < 5) n (x + 7 > 6).

{x | -1 < x < 7}
{all real numbers}
Ø

Answer 1

x - 2 < 5 = x < 7
x + 7 > 6 = x > -1

There is no overlap of these two range of numbers, so the intersection would be the empty set.

Answer 2

so a?

Answer 3

No, I think the empty set. The symbol in the middle looks like the intersection symbol, and the intersection would be Ø

Answer 4

oh ok thank you
