Slope of the point (10,5) and origin (0,0) is 
Step-by-step explanation:
Since we are given point (10,5) the other point will be origin i.e (0,0)
The formula used to find slope is:
Slope = 
here x₁ = 0, y₁ = 0, x₂=10 and y₂=5
Putting values in formula:
Slope =
Slope =
Slope =
So, Slope of the point (10,5) and origin (0,0) is

Answer:
230 were sold at the door
170 were sold in advance
Step-by-step explanation:
x=at door y=in advance
x+y=400
3x+2y=1030
y=-x+400
2y=-3x+1030
y=-3/2x+515
-x+400=-3/2x+515
x=230 y=170
Answer:
A. (x−2y)(y−3x)
=(x+−2y)(y+−3x)
=(x)(y)+(x)(−3x)+(−2y)(y)+(−2y)(−3x)
=xy−3x2−2y2+6xy
=−3x2+7xy−2y2
B. (2p+3)(p2−4p−7)
=(2p+3)(p2+−4p+−7)
=(2p)(p2)+(2p)(−4p)+(2p)(−7)+(3)(p2)+(3)(−4p)+(3)(−7)
=2p3−8p2−14p+3p2−12p−21
=2p3−5p2−26p−21
