From the graphs you can see that the graph of the line y= \frac{1}{3} x-3 lies under the graph of the line y= \frac{1}{3} x-1. Then all solutions of unequality y\le \frac{1}{3} x-3 are solutions of unequality y\le \frac{1}{3} x-1, but not all solutions of unequality y\le \frac{1}{3} x-1 are solutions of unequality y\le \frac{1}{3} x-3. 
For example, if x=1, y=-2
-2\le  \frac{1}{3} \cdot 1-1 =- \frac{2}{3} \\ -2\ \textgreater \  \frac{1}{3} \cdot 1-3=- \frac{8}{3}.
Answer: Correct choice is B.

The formula for the volume of a cone is V=1/3 pi r2h the radius r of the cone may be expressed as
Naily [24]

r = √(3V/πh)

multiply both sides by 3 to eliminate the fraction

πr²h = 3V ( divide both sides by πh )

r² = 3V/ πh ( take the square root of both sides )

r = √(3V/πh)

2x+3y=6 x+2y=5 elimination
ValentinkaMS [17]
In this equation you can eliminate the x value
multiply the second equation by -2 and you get:
-2x - 2y = -10 
when you add the two equations the x factors will cancel

   2x + 3y = 6
-  2x - 2y = -10 
---------------------
             y = 16

you can find the x value by plugging the y value that you now know into one of the equations that you started off with.
