Compare the strengths and weaknesses of the horizontal and vertical methods for adding and subtracting polynomials. Include comm

on errors to watch out for when using each of these methods.
Mathematics
1 answer:
Pavlova-9 [17]3 years ago
5 0

Answer:

Overall vertical is visually better, if done correctly

it forces you to "line up" all the common exponents.

The disadvantage is that it usually requires re-writing the problem, and it takes up space.

most problems are presented horizontally, that becomes the issue to locate the common exponents.

in both cases the biggest issue is people forget

that when subtracting "subtracting a negative is like adding a positive"

-5x - (-8x)  = 3x [that is a positive 3x]

or:

     -7x

-    - 10x

-------------

     3x

everyone misses those eventually so you have to watch out for that in both methods

Step-by-step explanation:

For a standard normal distribution, which of the following expressions must always be equal to 1?
frosja888 [35]
For a standard normal distribution, the expression that is always equal to 1 is P(z≤-a)+P(-a≤z≤a)+P(Z≥a). This expression represents all of the possible values in a curve, or in other words, the total area of a curve. According to standard normal distribution, the total area of a curve is always equal to 1.

Step-by-step explanation:

Use a ratio to solve:

miles : hours

300  :    6

250  :    5

 50   :     1

  x     :     3

x would be 150 miles

What are the domain and range of each relation?
torisob [31]

Order pairs  given coordinates on the graph: {(−3, 1), (−3, -4), (−1, 1), (1, -1), (4,4)}.


We need to find the domain and range.


<em>Domain of the order pairs are x values of each coordinate and range is the y values of each given coordinate.</em>


Each first value of order pair are the x values and each second value of each order pair are the y values.


In the given coordinates on the graph (−3, 1), (−3, -4), (−1, 1), (1, -1), (4,4), we can see first values are { -3,-1, 1, 4}


and we can see second values are { -4, -1, 1, 4}.

<h3>Therefore, Domain : { -3,-1, 1, 4} and </h3><h3>Range : { -4, -1, 1, 4}</h3>
