Answer:

3 is the correct answer (see explanations for each possible choice)

Step-by-step explanation:

1 cannot be right because 3 times smaller than 9 would be 3 as 1/3*9=3

2 cannot be right because 3 less than 9 is 9-3=6

3 is right because 3 times as much as 9 is 9*3=27

4 cannot be right because 3 more than 9 is 3+9=12

Step-by-step explanation:

First we eliminate any answers that can't be the answer.

2) can be eliminated because it implies subtraction instead of multiplication. Same with 4).

Now it is narrowed down to 1) and 3).

1) it is 3 times smaller than 9

3) it is 3 times as much as 9

It is not 1). The keywords 'times smaller' implies division.

So the answer is 3).

Hope it helps!

If g(3) = 5 and g(-1) = 5, explain why g(x) does not have an inverse.
Alenkinab [10]

g(x) cannot have an inverse because it gives the same output value for two individual input values.

In this case, g(x) is 5 when x is both 3 and -1. Hence, g(x) does not have an inverse.

Let me know if you have any questions, thanks!

For a finite sequence of nonzero numbers, the number of variations in sign is defined as the number of pairs of consecutive term
elena55 [62]

Answer:

The no. of variations in sign is 3

Step-by-step explanation:

Variation in sign occurs when every single time a negative product is produced by a pair of consecutive terms.

Therefore, the determination of the number of changes in sign in the given sequence is must.

Therefore, we take the product of the pair of consecutive terms as:

1\times (-3) = - 3, variation in sign

(-3)\times 2 = - 6,  variation in sign

2\times 5 = 10,  no sign variation

5\times (- 4) = - 20,  variation in sign

- 4\times (-6) = 24, no sign variation
