I hope this helps you



y=5x+6 this lines slope= -5


-3 (6x-y)= -54


6x-y= 18

y= 6x-18 this lines slope= -6


parallel lines slopes equal

-5 is not equal -6 not parallel

Answer:

lines are not parallel

Step-by-step explanation:

y = 5x + 6

–18x + 3y = –54

When the lines are parallel then the slope are equal

LEts write the equation in slope intercept form y=mx+b, where m is the slope

y= 5x+6

slope of the first line is 5

–18x + 3y = –54

Add 18x on both sides

3y= 18x-54

Divide whole equation by 3

y= 6x -18

Slope of the second line is 6

Slope of first line not equal to the slope of second line

So the lines are not parallel

Simplify
Scorpion4ik [409]

Answer:

1

Step-by-step explanation:

using the rule of exponents

(\frac{a}{b}) ^{-1} = \frac{b}{a} , then

\frac{123}{321} × \frac{456}{654} × \frac{789}{987} × \frac{321}{123} × \frac{654}{456} × \frac{987}{789}

[ \frac{123}{321} × \frac{321}{123} = 1 , \frac{456}{654} × \frac{654}{456} = 1 , \frac{789}{987} × \frac{987}{789} = 1 ]

= 1 × 1 × 1

= 1
