Question

solve by the elimination process
2x + 3y = 4
4x + 6y = 8
what is the solution of the system

Answer 1

hi jazil Do you have a selection of answer? i think its inconsistent here
2x + 3y = 4 if you want to eliminate x here, multiply by 2
4x + 6y =8

(2x + 3y = 4)2
4x + 6y = 8


4x + 6y = 8
4x + 6y = 8
------------
0 +0 = 0

Answer 2

so in other words there is no solution or there are definitely many solutions which one

Answer 3

it means that the two equations are the equally the same..either you substitute x or y, it will come up to be equal

Answer 4

can you graph this two equations?

Answer 5

graph them and you will find them to be the same equation

Answer 6

it does not tell you to graph
I have to tell what the solution of the system is by selecting
a. the solution is
b. there are infinitely many solutions
c. there is no solution

Answer 7

ok c, no solution

Answer 8

ok c, no solution

Answer 9

ok thats what i picked can you help me with this one please
solve and graph
1 - 3x >or=to 10 and 7x-5 > 30

Answer 10

1 - 3x >or=to 10 and 7x-5 > 30
- 3x >or=to 9 and 7x > 35
- x >or=to 3 and x>5
x <or=to -3

Answer 11

did you get it jazil?

Answer 12

Would the correct ans be {x|x-3<=tox<5} or {x|x<=to-3}
those are the two choices out of four to choose from and if one is correct where would the graph be meaning what end is the bracket and arrow

Answer 13

can you give me the other two choices pls?

Answer 14

sure
one is O with a line though it and {x|x>5}

Answer 15

{x|x<=to-3}
{x|x>5} these two are correct answer as we calculated there....lol

Answer 16

understand how i did the problem there and youl get them all.....lol

Answer 17

yep i was checking that out very well done
so on the graph i would choose the one with two parts correct with an arrow pointing to the left with a backet on right end and parenthese on left for other and arrow pointing to the right on end of this one am i right

Answer 18

yes correct put the arrow to the left for x <or=to -3
and the other x>5 it must be > than 5

Answer 19

and the other x>5 it must be > than 5, to the right

Answer 20

thanks thats what i did

Answer 21

ok jazil good luck and have fun.....

Answer 22

thanks for all your help tonight i learn a lot from you in such a short while i've been on for a little bit getting tired so i say nite nite
