Did you use the calculator provided on this website? is this algebra? what are you trying to do, factoring?
its algebra 2! and no which calculater do i use...its says to solve
the system of equations
solve by substitution? be specific?
it didnt say.. it just says solve system of equations
if it's Solve by Substitution Method: c=1
according to the calculator provided here.
okay so i plug 1 into all the c's?
a=-7b/4-5/4 b=2c/7-23/7 c=1 according to the calculator provided in this website.
that's if you are trying to Solve by Substitution Method:
is it correct?
idk i will find out what about this one it sayswithout graphing classify the following system as independent dependent or inconsistent
according to the calculator provided it is incosistent
okay thanks what about this one it says solve the systems of equattions useing matrix
it says x=7, y=5
just go to this website and solve for yourself http://www.freemathhelp.com/algebra-help.html scroll all the way down and you will find the calculator.
i dont understand how to use it help me with one more please
solve the system by elimination 4a+4b-c+=-6 8a+6b+c=-5 6z-4b-6c=-22
on the first equation after c+ then what?
ooops let me write it over its 4a+4b-c=-6
and the last one after the 6 its and a,,im in a hurry :)
you mean this on the last eq. 6z-4b-6a=-22
nooo the last one was 6a-4b-6b=-22
is it Solve by Addition/Elimination Method:?
if so then the calculator says can't be solve in addition method but on Solve by Gaussian Elimination: its (-11/6, 11/10, 46/15)
thanks what about this one: find the maximum valube of the objective function and the calues of x and y for which it occurs
f=2x+y 3x+5y(less than or greater then sign) 45 2x+4y(less than or greater then sign) 32
