Let r and s be binary relations on a set a. suppose that r is an equivalence relation and that s is symmetric, and transitive but is not reflexive. which statement is always true for any such r and s?
(a)r? s is symmetric but not reflexive and not transitive.
(b)r? s is symmetric but not reflexive.
(c)r? s is transitive and symmetric but not reflexive
(d)r? s is reflexive and symmetric

answer: y = -12x + 108

step-by-step explanation: do (y = m x+b) formula.

the median here is 25. your lowest value is 14 and highest value is 48. to find the third quartile, find the medium number in between 25 and 48 which would be 42 i believe.

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
