The table shows the record low temperatures for several states. Graph the temperatures on a number line.
OlgaM077 [116]

Step-by-step explanation:

Please find the attachment.

We have been given a table that shows the record low temperatures for several states. We are asked to graph the temperatures on a number line.

First of all we will draw a number line going to infinity into both directions.  

To graph the given temperatures on number line let us arrange temperatures in less negative order.  

-34, -32, -30, -29, -27.  

Since we know that numbers with large negative values lie on the left at number line. Let us graph our large negative temperature on the left at our number line.      

We can see that -34 is the most negative temperature, therefore, it will be on the left most side of our number line.  

-27 is greatest of our given negative temperatures. -27 is less negative temperature than our other given low temperatures, therefore, it will lie on the right most side of our number line.  

Other temperatures will lie between these two values according to their temperatures.    

-32 is second large negative temperature after -34, therefore, it will lie on the right side of -34.

-30 will lie on the right side of -32 and -29 will lie on the right of -32.

The solution to the system of equations:
castortr0y [4]

Answer:

1/2, 5/2

Step-by-step explanation:

Rearrange the system of equations.

-3x + y = -1

x + y = 3

Multiply the bottom equation by 3

3x + 3y = 9

Now add the two equations

4y = 10

y = 5/2

Now plug y back in to solve for x in one equation

x + y = 3

x + 5/2 = 3

x = 1/2

Answer in coordinates: 1/2, 5/2

Determine the positive<br> square root of 35, if it exists. Explain.
laila [671]
The positive square root of 35
= 5.9160797831 because 5.9160797831^2 is 35
Therefore you multiply 5.9160797831 to 5.9160797831
