Answer:
Perpendicular
Step-by-step explanation:
Given points P=(2,6) and Q=(4,5)
The line RS is y=2x-3.
Now we know that the line joining any two points (x1,y1) and (x2,y2) has slope m=
Now the slope of the line PQ is
m1=
= -
We know that the slope of the line in the form y=mx+c is m
So the line RS has slope m2=2
Now two lines are parallel if m1=m2
And those two lines are perpendicular if 
here m1= -
and m2=2
clearly 
Therefore the two given lines are perpendicular
1/4 hour is the same as 15 minutes. If it takes 15 minutes to paint 1/3, then it would take 45 minutes to paint the whole wall.
T = -20 so
t+1= -20 + 1
= -19
Answer:
I don't know if I understood the question correctly, but this is what I have...
Step-by-step explanation:
If the "x" is a variable:
(2x-3)-(1-1)=
2x-3
If th "x" is a multiplication sign:
(2x-3)-(1-1)=
-6-0=
-6
i hope this helps
