Answer:
1
Step-by-step explanation:
The slope of the perpendicular is the negative inverse of the slope of the line.
m = -1 / (-⅓)
m = 3
The slope between the two points is 3, so:
3 = (15 − 6) / (4 − n)
3 (4 − n) = 9
4 − n = 3
n = 1
factor took out was 
, And resultant expression is 
.
<u>Step-by-step explanation:</u>
Here we need to Take a factor out of the square root: sqrt(3y^2) , where y<0 .Let's do this :
The given expression is sqrt(3y^2) or , 
We know that , to take out a factor out of the square root that factor must have a degree in multiple of 2 , as 
etc . So ,
⇒ 
⇒ 
⇒ 
⇒ 
⇒
Therefore , factor took out was , And resultant expression is .
$=pn right? Because it's the price per mile, times the number of miles traveled.
Answer:
(8,-2)
Step-by-step explanation:
When reflecting something across the X axis the y axis coordinate is the one that will change to put the position further up or down. In this case we are moving it down to the same amount below the axis that it is now above it. That means that since it is currently 2 above the X axis it would then be 2 below the X axis making it at -2 so the coordinates would be (8,-2)
I hope this helps and please don't hesitate to ask if there is anything still unclear!
Split it up
3x^2+12x-5x-20
group
(3x^2+12x)+(-5x-20)
factor
(3x)(x+4)+(-5)(x+4)
undistribute (x+4) like ab+ac=a(b+c)
(3x-5)(x+4)
