Well they have to be perpendicual because they cross and parallel means that they are like lines on lines paper, they do not cross, they just keep going. Hope this helps :)
Well you do 228/12 to find your answer and that is 19 and to check you do 12*19=228

Answer:
x = 19
Step-by-step explanation:
you can set up a proportion among corresponding sides:
<u> 2x -14 </u> = <u> 18 </u>
32 24
18 /24 can be reduced to 3/4
<u> 2x - 14 </u> = <u> 3 </u>
32 4
cross-multiply: 4(2x - 14) = 32(3)
8x - 56 = 96
8x = 152
x = 19
Answer:
y=1/5x-3
Step-by-step explanation:
Start by finding the slope:
Slope = (y₂-y₁)/(x₂-x₁)
Now we plug in the coordinates:
Slope = (12-(-3))/(-3-0)=(12+3)/(-3)=15/-3=-5
The slope intercept equation would be
y=mx+b
Slope is m and y-intercept is b. x and y and the x and y-coordinates.
Now we plug in one of the x and y coordinate pairs into the equation:
-3=-5(0)+b
b=-3
So the equation of the line would be
y=-5x-3
<em>But the slope of a perpendicular line is the negative reciprocal of the original equation</em>
So...
y=1/5x-3
