5) Suppose on the first day of face to face classes I say If there is no parking in the lot by James Hall, then I
will be late for class but on the second day of class there is no parking but I am on time. Did my actions

Implies that this situation represents.
6) Which of the following statements are true and which are false? Explain why.
a) Vx  Z(3y  Z((x = 2y)V(x = 3y)))
b) Vx  R(3y R(y = vw))
c) Vx E ZEy E Z(y = x²))
7) Each of the following expressions represents a statement about the integers. Using p(x) for x is prime,
q(x, y) for x = y2″, r(x, y) for x < y," s(x, y, z) for z=xy, and t(x, y) for x=y," determine which expressions represent true statements and which represent false statements. a) Vx e z+(By Z+(r(x, y) 19(x, y))) b) Vx  Z+(Vy E Z+(q(x, y) =r(x,y))) c) Vx Z(vy ez (vz e z((s(x,y,z) At(x,y)) = a(z,y))) 8) Write a quantified statement for the zero-product rule. You may use p(x) for "(x + a)(x + b) = 0," q(x) for (x + a) = 0, f(x) for (x + b) = 0," and you may take as given that a and b are Real numbers. Purchase answer to see full attachment
