Step-by-step explanation:
The easiest approach is to realise that one hour is 3 times longer than
20
minutes. The longer the time, the more they will pave.

You could also use the 'unitary method' where you find out how much they pave in ONE minute (divide by
) and them multiply by
60
to find how much in one hour.

Answer:
APC is 90 degrees
When lines intersect and are perpendicular. that means the angle of intersection is 90 degrees.
(x,-y): (2,-2)
M=(x+x)/2,(y+y)/2
Given (1,4)=
This implies:
In a similar way,
The question demanded (x,-y)
Hence(2,-2) is the answer
Both graphs have a “y-intercept” at (0,0), so i believe the answer would be they don’t have y intercepts
