Using the symbolization key given below, symbolize each English sentence in FOL (First-Order Logic). Here is the key for inputting the logical connectives and quantifiers into Carnap:

type ~ or "not" for negation
type \/ or "or" for disjunction
type /\ or "and" for conjunction
type > or -> for conditional
type <> or <-> for biconditional
type Ax for the universal quantifier
type Ex for the existential quantifier
Here is the symbolization key:

Domain: people
C(x) = x knows the combination to the safe.
S(x) = x is a spy.
V(x) = x is a vegetarian.
h = Hofthor
g = Galadriel

Translate:
No one knows the combination to the safe unless everyone is either a spy or vegetarian.

step-by-step explanation:

answer: 59

step-by-step explanation:

the system of inequity is

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

the solid line passing through the points (0,4) and (4,0).

the related equation of solid line is .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

the related equation of dashed line is

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be . the required inequality is

similarly, check the second related equation.

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is
