Here is what we know:
8 machine parts
each part = x pouunds
packaging for each part is 2 pounds so 16 pounds for packaging

If y=total weight wiith that information we can form this equation 
y=8x + 16

If each part equals 6 pounds the total shipment will be
y=8x+16
y=8(6) + 16
y= 48 + 16
y=64

Which do the following equations represent? -4x-5y=-4 and 10x-8y=-1
kicyunya [14]
Parallel have same slope
Perpendicular have opposite reciprocal slopes. Ex. 2/3 is slope of one line so the perpendicular line would have slope of -3/2.

Find slopes of these lines.

-4x-5y=-4
-4x+4 =5y
Divide by 5

Y= -4x/5 +4/5

Second line: 10x-8y=-1

10x+1=8y
Divide by 8

10x/8 +1/8 =y

Y= 5x/4 +1/8

So if you look at slope of line 1= -4/5 and line 2 it’s 5/4 so these both are perpendicular.

#1

\\ \rm\Rrightarrow 2y=x-4

\\ \rm\Rrightarrow y=x/2-2

  • m=1/2

Parallel lines have equal slope

Equation in point slope form

\\ \rm\Rrightarrow y-4=1/2(x-1)

\\ \rm\Rrightarrow 2y-8=x-1

\\ \rm\Rrightarrow x-2y+7=0

#2

\\ \rm\Rrightarrow 1/2y-3x=2

\\ \rm\Rrightarrow 1/2y=3x+2

\\ \rm\Rrightarrow y=6x+4

  • m=6

Parallel lines have equal slope

Equation of line

\\ \rm\Rrightarrow y-6=6(x+2)

\\ \rm\Rrightarrow y-6=6x+12

\\ \rm\Rrightarrow 6x-y+18=0

#3

\\ \rm\Rrightarrow 1/k x+5=3y\implies y=x/3k+5/3

  • m1=1/3k

\\ \rm\Rrightarrow y=(2/k+3)x-6/(k+3)

  • m2=2/k+3

Slopes remain same

\\ \rm\Rrightarrow \dfrac{1}{3k}=\dfrac{2}{k+3}

\\ \rm\Rrightarrow k+3=6k

\\ \rm\Rrightarrow 5k=3

\\ \rm\Rrightarrow k=3/5
