Exercise Set 1.1p. 21

#4  Let x,y,a,b, and c represent real numbers. Determine if the given expression is a sentence.

a.)   x = y is a sentence. In fact, it is an open statement, because it has no truth value.

b.)   x + y is not a complete thought, it does not contain a verb, therefore it is not a sentence.

c.)   x < y is a sentence. In fact, it is an open statement, because it has no truth value.

d.)  x ÷ y is not a complete thought, it does not contain a verb, therefore it is not a sentence.

e.)  $\-b\pm\sqrt{b^2-4ac}$ is not a complete thought, it does not contain a verb, therefore it is not a sentence.
