Select either relation (if the set is a relation but not a function), function (if the set is both a relation and a function), o

galina1969 [7]

Answer: The correct options are

(A) relation

(B) function.

Step-by-step explanation: We are given to check whether the following set is a relation or a relation and a function or neither :

A = {(1, 2) (2, 2) (3, 2) (4, 2)} .

Let us consider the following two sets :

U = {1, 2, 3, 4} and V = {2}.

Then, we see that the Cartesian Product of U and V is given by

U × V = {(1, 2) (2, 2) (3, 2) (4, 2)}.

Since a relation is a subset of Cartesian product, so the given set A is a relation.

Also, we know that a relation is a function if every first element is associated with one second element.

Since the relation A satisfies this condition, so the relation A is a function.

Thus, the given set A is both a relation and a function.

Option (A) and (B) are correct.

How to solve the inequality

beks73 [17]

Answer:

x $\geq$ 19/6

Step-by-step explanation:

1. Multiply both sides by 6 (the LCM of 6,3)

5/2 + 3-x <= 2(x-2)

2. Simplify 5/2+3-x to 11/2-x

11/2 - x<=2 (x-2)

3. Expand.

11/2-x<= 2x-4

4. Add x to both sides.

11/2<= 2x-4+x

5. Simplify 2x-4+x to 3x-4.

11/2<=3x-4

6. Add 4 to both sides.

11/2+4<=3x

7. Simplify 11/2+4 to 19/2

19/2<=3x

8. Divide both sides by 3

19/2 /3 <=x

9. Simplify 19/2 /3 to 19/2*3

19/2*3<=x

10. Simplify 2*3 to 6

19/6<=x

11. Switch sides.

x>= 19/6

Hope this helps!

Can you simplify 3/18. EXPLAIN?

Sauron [17]

Answer:

Yes, it simplifies to 1/6.

Step-by-step explanation:

Both the top (numerator) and bottom (denominator) can be both divided by 3. 3 divided by 3 is 1. 18 divided by 3 is 6.

Answer this plz I dont know I think its h but IDK WHY. PLZ TELL ME THE ANSWER AND SHOW WORK PLZ. I'll give the brainliest answer

Bas_tet [7]

Your original answer is correct.If you set up a ratio table, it works. For example:
So, they amount of money she's taxed on is $55. We get this by doing 175-20.

$55 is equal to 106% because 6% is tax
Now, you want to find just 100% which is the same as no tax. To get from 106 to 11, you divide by 1.06. So, you also divide 55 by 1.06 to get $51.89
She can't go over this because she won't have enough money.

So, the answer is x≤$51.89
Hope this helps!
