Express the negations of each of these statements so that all negation symbols immediately precede predicates. a.∃z∀y∀xt (x, y, z) b.∃x∃yp(x, y) ∧ ∀x∀yq(x, y) c.∃x∃y(q(x, y) ↔ q(y, x))

the answer for this question is 38

no

step-by-step explanation:

2-7=-5

7-2=5

when you combing like terms for ech expression, 5 and -5. these numbers are not equal to each other.

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x
