Answer:

The first option

Step-by-step explanation:

I just found a place where the lines were on coordinate with whole numbers and replaces the x and y values of the equations (in this case I used 8,3). If the answer was correct, then that was the right equation

Answer:

1st option

x-4y=-4

3x +4y=36

Step-by-step explanation:

The point (8,3) is the common point for both lines (and their equations)

Let's pick another point for the red line, the I equation and then calculate the the equation

I (8,3) and (4,2)

m=\frac{3-2}{8-4}\\ \\  m=1/4

We now have the inclination angle = 1/4 crescent function

Looking at the graph we see the red line, the equation I intercepts y-axis on point 1

y=1/4x+1

y=1/4(8)+1 Therefore : y=3 Testing for (4,2) y=1/4*4+1 y=2

As for the blue line, the second equation finding out m, as we have two points for this Equation (0,9) and (8,3)

m=\frac{3-9}{8-0}\\  m=-3/4

y=-3/4x+9

So we have

y=1/4x+1

y=-3/4x+9

But in the options we have to multiply everything by four

4y=x+4

4y=-3x+36

Rearranging

-x+4y=4  *(-1)

3x+4y=36

Finally

x-4y=-4

3x +4y=36

Answer:

x = 3/2

Step-by-step explanation:

Let's solve your equation step-by-step.

(3)(1)+2x=6

Step 1: Simplify both sides of the equation.

(3)(1)+2x=6

3+2x=6

2x+3=6

Step 2: Subtract 3 from both sides.

2x+3−3=6−3

2x=3

Step 3: Divide both sides by 2.

2x/2  3/2

x = 3/2

Hope this helps :)

You may remember that the perimeter of a rectangle is P=2(W+L) where W is the width and L is the length. Suppose that the perime
Anna71 [15]

Answer:

5 feet

Step-by-step explanation:

P = 2(w + l)

P = 34

l = w + 7

34 = 2 (w + w + 7)

34 = 2w + 2w + 14

34 - 14 = 4w

20 = 4w

w = 5 feet

Since l = w + 7

l = 5 + 7

l = 12 feet
