Question

Please Help Math!!!

Answer 1

'm very stumped on this question and I don't know what to do! I have reviewed the lessons, but I just don't get it!


Please identify each relationship as direct or inverse. Next calculate the constant for each relationship. How are the two relationships different? How are they similar?
Relationship 1: x times y is 3

Relationship 2: *In the picture below*



Please help!! I need this answered quick!! :(

Answer 2

Do the two variables increase together (direct) or does one increase as the other decreases (inverse)?

Answer 3

Direct?

Answer 4

Please help anyone!! :c

Answer 5

No guessing. Did you answer my question? Do the two variables increase together?

Answer 6

Yes

Answer 7

Wait. No

Answer 8

No they don't

Answer 9

As the horizontal variable increases (moves to the right). What does the vertical variable do?

Answer 10

Decreases.

Answer 11

Are you talking about "Relationshp 1"?

Answer 12

Yes.....

Answer 13

Perfect. The relationship can be expressed as \(y = \dfrac{3}{x}\) and is a perfect model for INVERSE variation.

How about Relationship 2? Do the variables increase together or not?

Answer 14

Yes I believe so..

Answer 15

Perfect. Then it MIGHT be direct variation. There are two more requirements.

Is the relationship LINEAR?
Does the relationship include the point (0,0)?

If you can say yes to ALL THREE of those questions, it is direct variation.

Answer 16

Yes..

Answer 17

It appears to be y = 3x and is a lovely model for Direct Variation.

Very good.

Answer 18

Thanks for the help!!!
