The distacne between the points (x1,y1) and (x2,y2) is
so the distance between (4,5) and (10,13) is
well, first
x1=4
y1=5
x2=10
y2=13
so
D=√100
D=10
the distance is 10 units
6 I think
explanation
this is me trying fill in the 20 word required ment hope it helps
You would probably need to divide. <span>Inches
-------- = 30/3 = 10.

B) y = -2x
when x = a
y = -2a
when x= 2a
y = -2(2a) = -4a
Fh. = 40h + 120, fh. = $200
200 = 40h + 120
200 - 120 = 40h
80 = 40h
80/40 = h
2 = h
h = 2 hours.
