Given A = {x | x &lt; 1}, B = {x | x ≥ 5}, and C = {x | x = 5}, match the following items. 1. A B Ø 2. A C {x | x ≥ 5} 3. B C {x
ivann1987 [24]

Answer:

The matching is shown below.

Step-by-step explanation:

The given sets are defined as

A = {x | x < 1}

It means all the values of x which are less than 1.

B = {x | x ≥ 5}

It means all the values of x which are greater than or equal to 5.

C = {x | x = 5}

It means all the value of x is 5.

Union of two sets contains all the elements of both sets.

Intersection of two sets contains only common elements of both sets.

The matching is shown below.

        Sets                              Correct value

1.     A ∪ B                         {x | x < 1 or x ≥ 5}

2. A ∪ C                         {x | x < 1 or x = 5}

3. B ∪ C                         {x | x ≥ 5}

4. A ∩ B                         Ø

5. B ∩ C                         {x | x = 5}

Charlie weighs 9 pounds more than his little brother. If together they weigh 99 pounds what is the algebraic equation for Charli
Afina-wow [57]
To set up the equation you would take x and add the nine pounds that Charlie weighs more than his brother and the set that equal to 99. Your equation would be X+9=99. If you wanted to take it a step further and solve the equation you would distract 9 from both sides which means that x=90
