Answer:

Answer is given below under explanation

Step-by-step explanation:

We are told that the domain is a set of real numbers. Let's depict by a & b.

We will use the following symbols;

∀ means for all

Ǝ there exists

∧ means logical conjuction

Thus;

A) Ǝ a,b : ( a/b < 1, b/a < 1 )

B) ∀ a : ( a > 0 = 1/a > 0 )

C) Ǝ a,b : (a + b = ab)

D) ∀ a,b : [ ( a > 0 ) ∧ ( b > 0 ) = (( a/b > 0 ) ∧ ( b/a > 0 ))]

E) ∀ b : [( b > 0 ) ∧ ( b < 1) = ( 1/b > 1 )]

F) n ( ( Ǝ x ∀ b ( a < b ) )

lbvjy [14]

Answer:

1 - Option C - 10,000

2 - 3x+5 will be 12 more than 3x-7.

Step-by-step explanation:

1) To find : With what number must 3.475817 be multiplied in order to obtain the number 34,758.17?

Solution :

The number 3.475817 is multiplied by number to obtain 34,758.17.

As we see that, the decimal is moved four places to the right.

Which means the number is multiplied by 10000.

i.e. 3.475817\times 10000=34,758.17

Therefore, option C is correct.

2) To find : How much greater is the value of 3x+5 than the value of 3x−7?

Solution ;

Assuming that x is the same value in each equation,

In order to determine the difference between the two values,

We ignore the 3x part as it is the same on both of the equations.

So, from 5 to -7 i.e. 7+5=12.

Therefore, 3x+5 will be 12 more than 3x-7.
