Answer:

Step-by-step explanation:
Given that,
A line 7x - 3y = 68 and containing the point (8, -8).
The equation can be written as :

The slope is :7/3
Line is perpendicular so use m = –3/7

So, required equation is :

Answer:
The amount of white fabric to coloured fabric as a ratio is 20:11
Step-by-step explanation:
We are given that For each 11 mm of colored fabric Nick uses to make his curtains, he also uses 2 cm of white fabric.
Length of colored fabric = 11 mm
Length of White fabric = 2 cm
1 cm = 10 mm
2 cm = 20 mm
So, length of white fabric = 20 mm
So, Ratio of the amount of white fabric to coloured fabric = 
Hence the amount of white fabric to coloured fabric as a ratio is 20:11
Step-by-step explanation:
Perimeter of a Rect.= 2(l+b)
b= x
l= 2x
Equation
152= 2(2x+x)
152= 2(3x)
152= 6x
x= 25.33
2x= 50.66
Therefore length is 50.66m and breadth is 25.33m
The top left is the correct answer, because the sides are parallel.
Hope this helps!
I believe this would be correct.
