Question

Describe the difference between an open equation and a closed equation.


And on my last quest did steve mean 4,0 and 3, -2?

Answer 1

opps i meant 3, -1

Answer 2

Please help i need to get this done

Answer 3

I don't understand this -- but you might.

Answer 4

a closed equation is a statement of fact that may be true or false
eg
2 + 2 = 4 closed true
3 + 2 = 5 closed false

an open equation is one where it may or may not be true depending on the value of a variable
eg
x + 2 = 4

Answer 5

I do not know what you did with Steve

Answer 6

Okay thanks damon can you help em with this one?

Look at the following points.

(4, 0), (3, −1), (6, 3), (2, −4)

Which are solutions to y = x − 4? Choose all correct answers.

Answer 7

this is the one i dide with steve

Answer 8

the coices

(6, 3)
(4, 0)
(3, −1)
(2, −4)

Answer 9

(4, 0), (3, −1), (6, 3), (2, −4)

Which are solutions to y = x − 4

(4, 0)
0 = 4 - 4 true

(3, −1)
-1 = 3-4 true

(6, 3)
3 = 6 - 4 false


(2, −4)
-4 = 2 -4 false

Answer 10

okay thanks

Answer 11

:P here is my last on


How can you use an equation to make a prediction from a pattern?

Answer 12

here is what i think


lets say you want to find out the 267,000 letter or number in your pattern then you can just use that number plug it in your equation and find your letter or number

Answer 13

I am not sure what this is about. My guess would be what I call curve fitting the data. In the simple case you try to find the best straight line that goes more or less through the data points. If you do this by minimizing the sum of the squares of the differences between your line of form y = m x + b and the data points it is called "linear regression. However there are much more elaborate functions such as exponential and polynomial snd trigonometric and the problem can be extended to patterns in many dimensions.

Answer 14

Is my answer good?

Answer 15

Once you have your euation of form
y = m x + b
or
y = A sin x
or
y = a x^2 + b x + c
or whatever you think kind of fits the pattern,
Then you put in any old x you are interested in and get y

Answer 16

Yes, your answer is what I mean.

Answer 17

Okay thank you so much
