Question

If a = -12/5, then 5x + 2y = 6 and 3x - ay = 4 are parallel. How do I solve this?

Answer 1

What can you say about these two lines having equations:

2x + 3y = 9

And,

4x + 6y = 18

Answer 2

any guesses ??

Answer 3

Answer 4

Im not sure..

Answer 5

Solve what?

Answer 6

Is this a true/false problem?

Answer 7

It's a true or False question but i just want to know how i can determine how to figure it out.

Answer 8

Remember :-
Consider two lines :-
\[\large \bf a_1x+b_1y+c_1=0~and~a_2x+b_2y+c_2=0\]

Answer 9

If they are parallel,then use this :-
\[\large \bf \frac{a_1}{a_2}=\frac{b_1}{b_2}=\frac{c_1}{c_2}\]

Answer 10

^^^^^ `This is the condition for parallel lines`

Answer 11

Hmm, the second \(=\) should be \(\ne\)

Answer 12

The answer is that the equations aren't parallel so it's false?

Answer 13

with the help of above equation ,find out that they are parallel or not ??

Answer 15

That condition you said is for coincident lines. For parallel lines, you need to have no solutions.

Answer 16

yeah !! AGAIN SORRY !
