Answer:

a)  Reflexive, Symmetric, Not Transitive

Step-by-step explanation:

Given a\in N+2 we have that a\ge 2 and then \gcd(a,a)=a\ge 2 thus the binary relation is reflexive. To show that is symmetric note that for a,b\in N+2 we have \gcd(a,b)=\gcd(b,a) which implies the symmetric. In fact, the relation is <u>not</u> transitive, for example note that \gcd(7,7^2)=7 and \gcd(5^2,5) but \gcd(7,5)=1.

Ned help please number 25
zysi [14]

Answer:

$204.11

Step-by-step explanation:

To find 70% of $269.99, multiply $269.99 x .7 = $188.99.

To find the 8% sales tax on $188.99, multiply $188.99 x .08 = $15.12.

Add the $15.12 of sales tax onto the cost of $188.99 = $204.11

2x+3(2)=4<br> This is substitution. Please help I am stuck
Ber [7]

Answer:

x = -1

Step-by-step explanation:

2x + 3(2) = 4      

2x + 6 = 4           Multiply 2 and 3 to get 6.

2x = -2                Subtract 6 from both sides to isolate 2x.

x = -1                   Divide both sides by 2 to find x.

For what value of a does (1/7)^3a+3=343^a-1?
CaHeK987 [17]

Answer: ok, remember that when

x^a=x^b, when x=x, then a=b

also

x^-m=1/(x^m)

and

(x^m)^n=x^(mn)

so

we can rewrite 1/7 as 7^-1

so

and 343=7^3

7=7 so

-3a-3=3a-3

add 3a to both sides

-3=6a-3

add 3 to both sides

0=6a

0=a

a=0

Answer: 0
