Answer:

A line is passing through (-4,2) ( 4,-5)

First you need slope

slope = (-5-2)/(4+4) = -7/8

So, eq of line is

y-2 = -7/8 ( x+4)

y-2 = -7x/8 - -7/2

y = -7x/8 -7/2 +2

y= -7x/8 -3/2

So , OptionA)

Answer:

Northside

Median: 36

Range: 32

IQR: 17

Southside:

Median: 39

Range: 38

IQR: 22

Step-by-step explanation:

Northside first

Order the ages from least to greatest

24, 28, 32, 32, 32, 36, 41, 44, 49, 49, 56

Median is 36 since it's in the middle

Subtract the greatest number from the smallest number to find the range (56-24) = 32

To find the IQR you need the ages least to greatest

24, 28, 32, 32, 32, 36, 41, 44, 49, 49, 56

Find the lower quarter = 32

Find the upper quarter = 49

Subtract 49 and 32 (49-32) = 17

Southside

The Median is the line at the middle of the box, in this case its between 38 and 40 which is 39.

The range is 61 - 23 = 38 (Greatest - least)

The IQR is 52 - 30 = 22

Hope this helps!

Add the following polynomials:

JulijaS [17]

Add: (−x^3 + 26x^2 − 7x − 13) + (6x^4 − x^3 +8x + 27)

You may find it easier to write these one above the other:

 (−x^3 + 26x^2 − 7x − 13)
+ (6x^4 − x^3 +8x + 27)
-------------------------------------------
6x^4 -2x^3 + 26x^2 +x + 14 (answer)

Please note: You should use " ^ " to indicate exponentation.
6x4 −2x3 + 26x2 +x + 14 NO
6x4 −2x^3 + 26x^2 +x + 14 YES
