Step-by-step explanation:
Answer:
Step-by-step explanation:
let : x the length and y the width .... ( x > y and x ; y reals numbers )
the perimeter is : 2(x+y)
2(x+y) = 55...(1)
x/y = 7/4 ...(2)
by (2) : x = (7/4)y
subsct in (1) : 2( (7/4)y +y ) =55
(7/2)y +2y =55
multiply by 2
7y +4y = 110
11y = 110
y = 10
x = (7/4)(10)
x = 35/2
Since there are 1000 millilitres in 1 Liter. If we divide 25,000 by 1000 we get an answer of 25 Litres.
Answer:
Step-by-step explanation:
The slope of a line perpendicular to another line is the opposite reciprocal of the slope of the other line, meaning if the slope of the other line is
, then the slope of the line perpendicular is
.
Knowing this, we can start to construct the equation for the line:
![y = mx + b](https://tex.z-dn.net/?f=y%20%3D%20mx%20%2B%20b)
![y = 3x + b](https://tex.z-dn.net/?f=y%20%3D%203x%20%2B%20b)
To solve for
, we plug in the coordinates of the point that we know the line runs through,
:
![y = 3x + b](https://tex.z-dn.net/?f=y%20%3D%203x%20%2B%20b)
![1 = 3(2) + b](https://tex.z-dn.net/?f=1%20%3D%203%282%29%20%2B%20b)
![1 = 6 + b](https://tex.z-dn.net/?f=1%20%3D%206%20%2B%20b)
![b = -5](https://tex.z-dn.net/?f=b%20%3D%20-5)
Therefore, the slope of the line that is perpendicular ot the line provided in the equation is the following:
![y = 3x - 5](https://tex.z-dn.net/?f=y%20%3D%203x%20-%205)
