Answer:

y= -\frac{1}{2}x

Step-by-step explanation:

First, let's put the line in y=mx+b form

8x-4y=12

Subtract 8x over

-4y= -8x+12

Then divide everything by -4

y=2x-3

To find the perpendicular slope, negate the slope and flip the numerator and the denominator

Original Slope: 2/1

Flip: 1/2

Negate: -1/2

Then, use the point slop formula to find the equation of the line.

(y-y_{1\\})=m(x-x_{1})

Insert (0,0) in for x_{1}  y_{1} and -1/2 in for m

y-0= -1/2(x-0)

Distribute the -1/2

y-0= -1/2x+0

Add the 0 over

y= -1/2x

He length of a rectangle is three times its width. The perimeter of the rectangle is at most 112 cm.
g100num [7]
The equation relating length to width
L = 3W
The inequality stating the boundaries of the perimeter
LW <= 112
When you plug in what L equals in the first equation into the second equation, you get
3W * W <= 112
evaluate
3W^2 <= 112
3W <= 4 \sqrt{7}
W <= \frac{4 \sqrt{7} }{3} cm

So yeah if someone can help me with
Law Incorporation [45]

Answer:

y = x - 5

Step-by-step explanation:

The equation of the line parallel to the line $ ax + by + c_1 = 0$ is $ ax + by + c_2 = 0 $.

That is, equations of parallel lines differ only by constant.

The given equation is $ y = x + 4 $

This is written as $ x - y + 4 = 0 $

Therefore, the equation of the line parallel to this line is given by $ x - y + c = 0 $

The value of c is determined using the point given.

Substituting the point (3,-2) we get:

$ 3 + 2 + c = 0$

$ \implies c = -5 $

Therefore, the equation of the line becomes y = x - 5.
