Answer:

<h2>width = 3 feet</h2>

Step-by-step explanation:

Let h be the height of the door

and w be its width

The statement “The height of the door is I foot more than twice its width”

can be translated mathematically like this :  h = 2w + 1

Let’s solve the equation for w:

h = 2w + 1

⇔ 2w = h - 1

\Leftrightarrow w=\frac{h-1}{2}

now , if the door is 7 feet high then it’s width is equal to :

\Rightarrow \frac{7-1}{2} =\frac{6}{2} =3 \ ft

Answer:

<u>3 feet</u>

Step-by-step explanation:

It mentions that the height of the door is 1 foot more than twice its width.

  • height (h) = 2 × width (w) + 1 foot

The width of a door of <u>height 7 feet</u> will be :

  • 7 feet = 2 × width (w) + 1 foot
  • 2× width (w) = 6 feet
  • width (w) = <u>3 feet</u>

A line parallel to the line 3x+4y+8=0 with y-intercept 4
Vitek1552 [10]
3x + 4y + 8 = 0
4y = -3x - 8
y = -3/4x - 2....slope here is -3/4. A parallel line will have the same slope.

y = mx + b
slope(m) = -3/4
y int (b) = 4

so ur equation is : y = -3/4x + 4

What is the constant of variation, k,
ValentinkaMS [17]
The K-constant variation is the factor of the increase-decrease relationship between the x-variable and y-variable which can be stated as y=k*x or x=y/k<span>. For example, if y variable equal 5 and the x variable equal 2 then the k-constant variation equal 2 (calculation y=k*x --> 5=2*2.5). This constant shows the relationship between the variables.</span>
