Question

decide whether the pair of lines is parallel, perpendicular, or neither
5x+3y=6
5x+3y+9

Answer 1

parallel

Answer 2

Parallel, if I assume correctly that you mean
\[l: z=5x+3y+6\]and
\[k: z=5x+3y+9\]
The two lines will each travel in the same direction, they will only start at a different position on the z-axis. With these particular two equations, line k would be 3 points higher on the z-axis than line l.

Answer 3

i think you're assuming incorrectly

Answer 4

he stated no z's therefore he is referring to a system in R2 not R3

Answer 5

she's*

Answer 6

plus her previous questions imply that her grade level is between 8 and 10, not university or calculus 2 or 3. just sayin

Answer 7

i thiink she meant 5x+3y=9

Answer 8

you're trying to correct the first equation to mean
5x+3y+6

Answer 9

instead

Answer 10

thanks for the attack matt, Im 4 months from finishing my associates degree with a 3.79 GPA. Unfortunately I am terrible at algebra, everbody has weaknesses.

Answer 11

and yes it was = not + ust a typo

Answer 12

just*

Answer 13

Then I stand corrected, and am not sure whether it is indeed parallel, perpendicular or none.
