Answer:
The statement is true that a function is a relation in which each y value has ONLY 1 x value.
Step-by-step explanation:
The statement is true that a function is a relation in which each y value has ONLY 1 x value.
The reason is very clear that we can not have the repeated x-values (two same x-values).
For example, given the set of the ordered pairs of a relation
{(3, a), (6, b), (6, c)}
As the same x values (x=6) has two different Y values. Hence, the stated relation is not a function.
In order to be a function, a relation must have only 1 x-value for each y-value.
Therefore, the statement is true that a function is a relation in which each y value has ONLY 1 x value.
The answer to the equation is the second option.
Answer:
a) y=2x+4 b) 2 c) 6 d) Sorry, you'll have to do that buy it's not too difficult! ^u^
Step-by-step explanation:
Ⓗⓘ ⓣⓗⓔⓡⓔ
1a) Well, if you add the y to both sides, you would get y=2x+4
1b) Since the main form is y=mx+b with m being the slope, the slope in y=2x+4 must be 2
1c) 6, because if x is 1, 2(1)+4=6
1d) I'm afraid you'll have to do that, just substitute in different numbers for x

Please, please give brainliest, it would be greatly appreciated, I only need one more before I advance, thanks!
Answer:
Independent Variable: Jazz music
Dependent Variable: Sleeping Time
Experimental Group: people sleeping with jazz music
Control Group: people sleeping without jazz music
3 constants:
No of people in group
Jazz music
Sleep
Step-by-step explanation:
The independent variable is the one which is not altered by any outer influence. For example the jazz music will not be interrupted by the sleeping habits of people.
The dependent variable is the one which is affected by external changes such as sleeping time is afffected by external music or noises.
Experimental group on which experiment is being carried out.
Control group is which determines the changes in experimental group.
Constants which do not change for the number of experiment, could be number of people, type of jazz music, volume of jazz music also sleep is a constant .
