You have a line:
y=mx+b (slope-intercepted form)
m=slope of this line.
The slope of a line perpendicular to that given line will be: ´"m´"
m´=-1/m.
For example:
y=8x+3
m=8
The solpe fo a line perpendicular to "y=8x+3" is:
m`=-1/8
Answer:
Get a line of which you want to know the slope. Make sure that the line is straight.
Pick any two coordinates that the line goes through. Coordinates are the x and y points written as ( x, y ).
Pick which point's coordinates are dominant in your equation. ...
Set up the equation using the y-coordinates on top and the x-coordinates on bottom.
Let x = inches of snow reidville gets
12x = inches of snow greenboro gets
x + 12x = 65
13x = 65
x = 5
Reidville gets 5 inches of snow.
Answer:
(n/4) - 5 = 2(n-14)
Step-by-step explanation:
let the number be n
"25% of n" : (25/100)n = n/4
"Five less than 25% of n" : (n/4) - 5
"difference between the number and 14" : n - 14
" twice the difference between the number and 14" : 2(n-14)
Assembling all the parts:
(n/4) - 5 = 2(n-14)
