Question

Can someone help me with some math problems?

Answer 1

hey

Answer 2

general eq.of plane is Ax+By+Cz=D
because (3,0,0) lies on it
3A+0+0=D
3A=D
\[A=\frac{ D }{ 3 }\]
similarly find the value of B and see
and put in general eq.
simplify you get an eq. of plane free of A,B,C,D

Answer 3

no

Answer 4

correction ,it is not see but C

Answer 5

u wont eliminate 4 vars with 3 eqn

Answer 6

you will eliminate all four.

Answer 7

first please complete it.then you will see.

Answer 8

can you show me the values of B and C

Answer 9

no u silly ull just get a,b,c as functions of d

Answer 10

\[A=\frac{ D }{ 3 },B=?,C=?\]
please be soft ,don' only say first find the values.

Answer 11

I don't know this.
@mathmate can you help with this?
@3mar you may help

Answer 12

i know how to do it, but the asker is not here

Answer 13

we should wait for them to return before helping

Answer 14

0+8B+0=D
\[B=\frac{ D }{ 8 }\]
0+0+6C=D
\[C=\frac{ D }{ 6 }\]
\[\frac{ D }{ 3 }x+\frac{ D }{ 8 }y+\frac{ D }{ 6 }z=D\]
divide each term by D

Answer 15

oh nice

Answer 16

i have learnt my lesson

Answer 17

it is good you learnt your lesson.

Answer 22

\[\frac{ x }{ 3 }+\frac{ y }{ 8 }+\frac{ z }{ 6 }=1\]
multiply by L.C.M. of 3,8,6 i.e.,24
8x+3y+4z=24

Answer 23

@maddieayeeee

Answer 24

can you help

Answer 25

So, 8x+3y+4z=24 is the final equation? Could u graph this?

here you go, you could use this to help your answer

Answer 27

Hopefully it helps

Answer 28

Ty, How do i graph this?

Answer 29

Isent it supposed to be on a graph?

Answer 30

yes, but it is three dimensional.

Answer 31

ooo

Answer 32

so i can just draw something just like that, with no graph?

Answer 33

yes,but you can take points A,B,C on scale

Answer 34

on scale?

Answer 35

Sorry, I was not here!

Answer 36
