show that the relation R in R define as R = {(a, b): a<_ b}, is reflexi when transistor but not symmetry

kati45 [8]

Answer:

R is reflexive and transitive but not symmetric.

Step-by-step explanation:

R = {(a, b); a ≤ b}

Clearly (a, a) ∈ R as a = a.

R is reflexive.

Now,

(2, 4) ∈ R (as 2 < 4)

But, (4, 2) ∉ R as 4 is greater than 2.

R is not symmetric.

Now, let (a, b), (b, c) ∈ R.

Then,

a ≤ b and b ≤ c

→ a ≤ c

→ (a, c) ∈ R

R is transitive.

Thus, R is reflexive and transitive but not symmetric.

Which algebraic expression repesents the phrase? Cindy studied seven more hours than Nikki studied. a. n+7 b. 7-n c. 7n d. n/7

elixir [45]

Answer:

Option a is the correct choice.

Step-by-step explanation:

Let n be number of hours studied by Nikki.

We are told that Cindy studied seven more hours than Nikki studied. This means that number of hours studied by Nikki plus 7 hours equals to the number of hours studied by Cindy.

We can represent this information in an expression as :

$\text{The number of hours studied by Cindy}=n+7$

We can see from our given choices that expression given in option a represents the number of hours studied by Cindy in terms of hours studied by Nikki.

Therefore, option a is the correct choice.
