Hell quic .. i have more coming too . plz
given: x = 5 ( mod 13 )
which of the following integers are valid solutions for x ?
choose all answers that apply:
(choice a)
a
-21
(choice b)
b
5
(choice c)
c
17
(choice d)
d
29
(choice e)
e
31
(choice f)
f
none of the above

Choice B : 5

Step-by-step explanation:

The question belongs to modular arithmetic. When two integers are divided , we get an equation like:

A/B=Q remainder R

Sometimes, the remainder is more important. For that purpose, we use “mod” (Modulus operator)

The modulus operator gives us the remainder when two integers are being divided i.e. if we have an expression like

14 mod 6= ?

We will get the answer, the remainder as 2.

So for the given question,

x=5 (mod 13)

As the number that is being divided by 13, a number greater than the divisor, the quotient will be zero and the remainder will be 5.

So

x=5

So choice B is the correct answer.

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

think about it deeply and passionately about this property

i am sorry
