5x+6y=18and 18x-15y=36 parallel or perpendicular

Katen [24]

Answer:

They are neither parallel nor perpendicular, since slope are different and not related by any equation

Step-by-step explanation:

First arrange them according to general equation:

$y = mx + c$

for the first equation :

$5x + 6y = 18 \\ 6y = - 5x + 18 \\ { \boxed{y = - \frac{5}{6} x + 3}}$

for the second equation :

$18x - 15y = 36 \\ 15y = 18x - 36 \\ y = \frac{18}{15} x - \frac{12}{5}$

What does "a"equal to?

slamgirl [31]

Distribute on the left side
7.4a+22.2=3.2a+43.2
Subtract 3.2a from both sides
4.2a+22.2=43.2
Subtract 22.2 from both sides
4.2a=21
Divide both sides by 4.2
a=5
