Select all true statements. The statement p V [-p ^ q)] is a tautology.
The statement (p V q) (q^ns) is logically equivalent
to (-9 V s) — (p^-9)
If (P1 AP2 P3) — q is a valid argument, then so is
(P1 AP2 AP3 A24) - q for any statement P4.
In the statement "If you are good at logic, then you can answer
this question correctly", being good at logic is a necessary
condition for answering this question correctly.

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
