The correct answer is: D. (A u B)

Step-by-step explanation:

The operations on sets are of two types

1. Union

2. Intersection

In union, the elements of both sets are combined in one set while in intersection only common elements of both sets are considered.

Here,

"all of the elements which are in set A or B"

This statement means the elements of both sets have to be considered. The word "Or" points to the combination of both sets as an elements belonging to any of the set will be considered. So union operation will be used.

Hence,

The correct answer is: D. (A u B)

Is -13 less than f/2

LenKa [72]

Answer:

Yes, -13 is less than f/2.

Step-by-step explanation:

Since we are given a fraction with a variable, it may seem hard at first to find out which number is greater.

First, we have to realise that -13 is a negative number. Any negative number is always equal to less than a positive number.

Whatever number we replace our variable f with, whether it be 2, 3, 9, or 0.00000000000001, we can rest assure that it will be a positive number.

Since positive numbers are greater than negative ones, -13 has to be less than f/2.

If the fraction was negative (- f/2), this would be a nearly impossible question to answer.

What is the value of 12x^-3 y-1 for x=-1 and y=5 A.-12/5 B.-180 C.-60 D.-5/12

Mkey [24]

Expressions are mathematical statements represented with the variables

The value of 12x^-3 y-1 for x=-1 and y=5 is - 12/5

<h3>How to determine the value of the variable</h3>

The expression is given as:

$12x^{-3} y^{-1}$

When x = -1, the expression becomes

$12 * -1^{-3} y^{-1}$

Evaluate the exponent

$- 12 y^{-1}$

When y = 5, the expression becomes

$- 12 * 5^{-1}$

Evaluate the exponent

- 12/5

Hence, the value of 12x^-3 y-1 for x=-1 and y=5 is - 12/5
