- Unit 1: Logic 1. Let P be the statement "x > 5” and let Q be the statement “y +3≤ x," and let R be the statement “y Є Z.” (a) Translate the following statements to English. (b) Negate the statements symbolically (c) Write the negated statements in English. The negations should not include any implications. • (QV¬R) AP • (P⇒¬Q) VR • (PVQ)¬R 2. Let R, S, and T be arbitrary statements. Write out truth tables for the following statements. Determine whether they are a tautology or a contradiction or neither, with justification. ⚫ (RAS) V (¬R ⇒ S) (R¬S) V (RAS) • (TA (SV¬R)) ^ [T⇒ (R^¬S)]arrow_forward10. Suppose the statement -R (SV-T) is false, and that S is true. What are the truth values of R and T? Justify your answer.arrow_forward5. Rewrite the statements below as an implication (that is, in "if... then..." structure). n is an even integer, or n = 2k - 1 for some k Є Z. x²> 0 or x = 0. 6.

Then (where appropriate) indicate whether the orig- inal statement is true, or the negation is true. ⚫ If I take linear algebra, then I will do my homework or go to class. • (x > 2 or x < −2) ⇒ |x| ≥ 2 • P⇒ (QVR) ⇒(¬PV QV R) Vn EN Em E Q (nm = 1) • Ex E N Vy & Z (x. y = 1)arrow_forward8.
