Answer:

x = -1

Step-by-step explanation:

y + 2x = -1

Subtract 2x from both sides;

y = -2x - 1

y = 3x + 4

-2x - 1 = 3x + 4

Subtract 3x from both sides;

-5x - 1 = 4

Add 1 to both sides;

-5x = 5

Divide both sides by -5

x = -1

Answer:

All 600 members of the club are population of this study

Step-by-step explanation:

There is difference in population of study and the samples taken from that population. All the 600 members of the club are actually the population of this study whereas the 50 members taken out of these 600 members are basically the sample of data. In order for us to carry out the surveys easily, we select a sample from the whole population. The sample has smaller number as compared to the whole population making it easier for us to carry out survey.

Is 9x=270 addition property of equality or symmetric property?
Ede4ka [16]
This is the symmetric property, for you divide 9 to both sides to get x, instead of adding (addition property of equality)

So symmetric property should be your answer
Hope this helps

Statement 1 is false.

While it is true that some of the y-values have more than one corresponding x-value, this does not make the relation not a function.  It would not be a function if some of the <em>x-values</em> had more than one corresponding y-values.

Statement 2 is true.

The domain of a function is all the x-values it encompasses.  This function starts at 3 and ends at 8.

Statement 3 is false.

The range of a function is all the y-values it encompasses.  This includes all the y-coordinates, but it does not express the range properly.  The range is [6, 10].

Hope this helps!!
