Answers

Answer:

So, the solution to the equation

log(7)+log(x−4)=log(7)+log(x−4)=1 is x=38/7

, which is approximately 5.43 when rounded to two decimal places.

None of the options provided (38, -18, 18, 3998) match this solution.

Step-by-step explanation:

Which of the sets of ordered pairs represents a function?A = {(1, −2), (3, −5), (5, 2), (7, 5)}

B = {(4, 2), (4, −2), (9, 3), (9, −3)}


only A
only B
Both A and B
neither A or B

Answers

Answer:

Option A is correct.

only set A is the ordered pairs represents a function.

Step-by-step explanation:

By the definition of a function, for each input there exists a unique output.

In particular, for each value of x there exists unique value of y.

In set A,

we have four ordered pair (1, -2) , (3, -5) , (5, 2) and (7, 5)

For each input value of x in set A,  there is a unique value of y in set A.

therefore, Set A is a function.

In set B,

we have four ordered pair (4, 2) , (4, -2), (9, 3) and (9, -3)

which means for x=4 , we have two values of y, i.,e 2 and -2

⇒ for a single value of x , there exist more than one value of y,

therefore set B is not a function


It's only A, because for each x, there's only one y, unlike B where there are two values for x=4 and two for x=9.

Which statement is an example of the Identity Property of Multiplication? 8 • 0 = 0
8 • 1 = 8
8 • –1 = –8
–8 • –1 = 8

Answers

Option 2 - 8 x 1 = 8 is the correct alternative.

We have the options as mentioned in the question.

We have to determine which is an example of Identity Property of Multiplication.

What is Identity Property of Multiplication ?

The identity property of multiplication says that the product of 1 and any number is that number.

According to the question -

Using the Identity Property of Multiplication -

8 x 1 = 8

Hence, Option 2 is the correct alternative.
