Traffic rules are set by each individual state.
In most states, an intersection where traffic lights are out of order
is treated as if it were a 4-way STOP.
But you can't depend on this answer. You MUST determine what
the law is in the state where you're driving. And if you drive out of
state, it may change for you.
1a. It does say y is "less than 8", which means 7, 6, 5, 4, etc. So it should be y < 8, with the arrow going from 8 to the the left.
Everything else in 1 is correct.
For 2, you're just picking out which of the given numbers satisfy the inequality, for example
a. 14, 15, 16 are solutions. 13 is not because it is less than 14.
3. Same thing as 1

I'm assuming you meant this. (6*7) - (3^2) *(9+4^3)
(42) - (3^2) * (9+4^3)
(42) - (9) * (9+4^3)
(42) - (9) * (9+64)
(42) - (9) * (73)
42 - 657
-615
Hope this helps!
