Which statements are true about the rules of multiplication for signed numbers? Check all that apply. The product of two negativ

blsea [12.9K]

Answer:

A, C, D

Step-by-step explanation:

As important rules of thumb that you should remember:

- the product of 2 negatives ALWAYS makes a positive

- the product of 2 positives ALWAYS makes a positive

- the product of 1 positive and 1 negative ALWAYS makes a negative

Now, look at the answer choices:

- "The product of two negative integers is positive" this is true

- "The product of two integers with different signs is positive" this is essentially saying that the product of a positive integer with a negative integer is positive, which is false

- "If two numbers are the same sign, then the product is positive" this is true, as can be seen by the first two bullet points at the beginning

- "The product of a positive and a negative is negative" this is true

- "If the signs of two integers are different, then the product is positive" this is false because of the third statement above

The answers are A, C, and D.

Solve the inequality.

borishaifa [10]

2>8-4h/3 subtract 8 from both sides

-6>-4h/3 multiply both sides by 3

-18>-4h divide both sides by -4 (and reverse sign because of division by a negative value)

4.5<h or by convention...

h>4.5

Determine algebraically whether the function is even, odd, or neither even nor odd. f as a function of x is equal to x plus quan

xenn [34]

Answer:

1) Even for first problem.

2) Neither for the second.

I really think the problem I labeled 1 is the correct interpretation but just in case you meant the latter I wrote the latter as well. The sentence translates to exactly what I have for problem number 1.

The Problem:

1) Determine if $f(x)=x+\frac{4}{x}$ is even, odd, or neither.
