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)
to have 2.40$ between 30 dimes and nickels she would have to have 18 dimes being 1.80$ and 12 nickles being .60 cents.
Subtract 2 from each side of the equation, and
the answer will be right there, staring up at you.

Answer:
Step-by-step explanation:
Number of tickets for international flights = 36
Total number of tickets = 95
The probability that a randomly selected airline ticket is for an international flight = 36 / 95 = 0.3789
The probability that a randomly selected airline ticket is for an international flight as a percent rounded to the nearest tenth of a percent = 0.3789 x 100 = 37.9%
% of males surveyed = 0.236 + 0.218 = 0.454 = 45.4%
% of males surveyed who prefer chicken = 0.236 out of 0.454 = 0.236 / 0.454 = 0.5198 = 51.58% = 52.0%
