What are the cons of graphing, elimination, and substitution?

Mathematics

GRAPHING CONS

1) hard to graph by hand. Often you need a graphics calculator or a computer software like maple or matlab. Or the graph has to be given.

2) hard to tell the exact solution, just by observing point of intersection. for example if x = 2.8675, the viewer would say x= 3.

3) sometimes not easy to decide the axis window of y and x axis. For example if the solution is very large like x = 100000 and your graph ends at x = 100, you cannot see the solution

SUBSTITUTION CONS

1) Becomes tedious if a system has too many equations or variables

ELIMINATION PROS/CONS

1) basically same as substitution

Find the solution set of this equation.<br> y^2-11y=0 <br> separate the two values with a comma.
Tanya [424]

Answer:

0,11

Step-by-step explanation:

y^2-11y=0

y(y-11)=0 we have transformed the equation into a product

a product can be zero only if one of the factors is 0

so the two solutions are

y=0

and y-11=0  y=11

The Carter Motor Company claims that its new sedan, the Libra, will average better than 31 miles per gallon in the city. Assumin
Nutka1998 [239]

Answer:

The null hypothesis   H_o :  \mu =  31

The alternative hypothesis H_a :  \mu >  31

Step-by-step explanation:

From the question we are told that

  The population mean is  \mu =  31 \  miles / gallon

Generally

   The null hypothesis is that the company's  new sedan, the Libra, will have an average of   \mu =  31 \  miles / gallon

This mathematically  represented as

The null hypothesis   H_o :  \mu =  31

   The alternative hypothesis is that the company's  new sedan, the Libra, will have an average better than   \mu =  31 \  miles / gallon

This mathematically  represented as

     The alternative hypothesis H_a :  \mu >  31
