two points are (0,0) and (100, -800)
m = (y2-y1)/(x2-x1) = (-800-0)/(100-0) = -8
point slope form of the line is
y-y1 = m(x-x1)
y-0 = -8 (x-0)
y=-8x
this is in slope intercept form now
y=-8x
Answer:
Step-by-step explanation:
Answer:
Option A - 
Step-by-step explanation:
Given: The volume of a cylinder = 
Let us substitute the volume of cylinder in the formula.
The formula for volume of a cone is 
(1)
The formula for volume of a cylinder is 
(2)
Substituting 
in equation (2), we get,
Given that the cone has the same radius and height of that of the cylinder, let us substitute 
in equation (1)
Thus, the volume of a cone with the same radius and height of a cylinder is .
Answer:
70 and 110
Step-by-step explanation:
The two angles add to 180 degrees since they form a straight line
2x+10 +3x+20 =180
5x+30 = 180
Subtract 30 from each side
5x+30-30 =180-30
5x = 150
Divide by 5
5x/5 =180/5
x = 30
The left angle is 2x+10 = 2*30+10 = 60+10 =70
The right angle is 3x+20 = 3*30 +20 = 90+20 = 110
