$-2y=-x+8\qquad\text{divide both sides by (-2)}\\\\y=\dfrac{1}{2}x-4\\\\for\ x=0\to y=\dfrac{1}{2}(0)-4=0-4=-4\to(0,\ -4)\\\\for\ x=2\to y=\dfrac{1}{2}(2)-4=1-4=-3\to(2,\ -3)\\\\for\ x=4\to y=\dfrac{1}{2}(4)-4=2-4=-2\to(4,\ -2)$

Martha has 8 cubic feet ofputting soil in the three flowerpots she wants to put the same amount of soil in each pot how many cub

frozen [14]

Answer:

$2\frac{2}{3}\text{ ft}^3\approx 2.67\text{ ft}^3$

Step-by-step explanation:

We have been given that Martha has 8 cubic feet of putting soil in the 3 flowerpots. She wants to put the same amount of soil in each pot.

To find the amount of soil in each pot, we need to divide total soil (8 cubic feet) by number of pots (3) as shown below:

$\text{Amount of soil in each pot}=\frac{8\text{ ft}^3}{3}$

$\text{Amount of soil in each pot}=2\frac{2}{3}\text{ ft}^3$

$\text{Amount of soil in each pot}=2.6666\text{ ft}^3$

$\text{Amount of soil in each pot}\approx 2.67\text{ ft}^3$

Therefore, Martha needs to put approximately 2.67 cubic feet of soil in each flower pot.
