Ax + by + c = 0, k = - a/b.
so The slope of the first line = ,
the slope of the second line = ;
So these two lines are parallel and they don't intersect
Answer:
Step-by-step explanation:
So here we have a 45-45-90 triangle.
This a special right triangle were the sides across from the 45 degree angles can be considered x, while the hypotenuse is two square roots of x.
Here since we have the sides across from the 45 degree angle we can conclude that
So if we wanted the hypotenuse we would just plug in this value of x like so:
Therefore the hypotenuse is 18.
Since you keep proportional dimensions, the proportion between the old and new dimensions must be the same. So, if we call the new height , the preservation of the width/height ratio is written as
Solving the proportion for yields
