Answer:
Step-by-step explanation:
1) Parallel lines have same slope
y = 3x + 2
m = 3
(2, -4) ; m = 3
equation: y - y1 = m (x - x1)
y - [-4] = 3(x - 2)
y + 4 = 3x - 6
y = 3x - 6 - 4
y = 3x - 10
2) y = 18x + 2
m1 = 18
Slope the line perpendicular to y = 18x + 2, m2 = -1/m1 = -1/18
m2 = -1/18
(1 , -5)
![y-[-5]=\frac{-1/18}(x-1)\\\\y+5=\frac{-1}{18}x + \frac{1}{18}\\\\y=\frac{-1}{18}x+\frac{1}{18}-5\\\\y=\frac{-1}{18}x+\frac{1}{18}-\frac{5*18}{1*18}\\\\y=\frac{-1}{18}x+\frac{1}{18}-\frac{90}{18}\\\\y=\frac{-1}{18}x-\frac{89}{18}\\\\](https://tex.z-dn.net/?f=y-%5B-5%5D%3D%5Cfrac%7B-1%2F18%7D%28x-1%29%5C%5C%5C%5Cy%2B5%3D%5Cfrac%7B-1%7D%7B18%7Dx%20%2B%20%5Cfrac%7B1%7D%7B18%7D%5C%5C%5C%5Cy%3D%5Cfrac%7B-1%7D%7B18%7Dx%2B%5Cfrac%7B1%7D%7B18%7D-5%5C%5C%5C%5Cy%3D%5Cfrac%7B-1%7D%7B18%7Dx%2B%5Cfrac%7B1%7D%7B18%7D-%5Cfrac%7B5%2A18%7D%7B1%2A18%7D%5C%5C%5C%5Cy%3D%5Cfrac%7B-1%7D%7B18%7Dx%2B%5Cfrac%7B1%7D%7B18%7D-%5Cfrac%7B90%7D%7B18%7D%5C%5C%5C%5Cy%3D%5Cfrac%7B-1%7D%7B18%7Dx-%5Cfrac%7B89%7D%7B18%7D%5C%5C%5C%5C)

Answer:
20/3 ft or 6 2/3 ft
Step-by-step explanation:
A = 56 2/3 sq ft
W = 8 1/2 ft
L = ?
A = LW
L = A/W
Change the mixed numbers into fractions.
Answer: 20/3 ft or 6 2/3 ft
You have to find a common denominator first.
The answer will be x=-3 y=-4
