Change the form to slope-intercept form (basically solving for y)
4x - 6y = 12
-6y = -4x + 12
y = 4/6x -2
y = 2/3x - 2
The slope is what is attached to the x variable, which is 2/3
Answer: ![A_2=\frac{\pi(2D)^{2}}{4}](https://tex.z-dn.net/?f=A_2%3D%5Cfrac%7B%5Cpi%282D%29%5E%7B2%7D%7D%7B4%7D)
Step-by-step explanation:
1. You have the following formula for calculate the area of the original circular chip:
![A_1=\frac{\pi(D)^{2}}{4}](https://tex.z-dn.net/?f=A_1%3D%5Cfrac%7B%5Cpi%28D%29%5E%7B2%7D%7D%7B4%7D)
Where D is the diameter of the circle.
2. Then, if the diameter of the original circular chip is doubled (2D) to use in a new board game, the area of the new chip can be calculated with the following formula:
![A_2=\frac{\pi(2D)^{2}}{4}](https://tex.z-dn.net/?f=A_2%3D%5Cfrac%7B%5Cpi%282D%29%5E%7B2%7D%7D%7B4%7D)
Answer:
I think it is 6
Step-by-step explanation:
2x-y=5x+3y=7
-3y -3y
2x-4y=5x=7
-2x -2x
-4y=3x=7
-4+3=-1=7
7-1=6
Answer:
1 : 15
Step-by-step explanation:
1,5 l of water = 1500 ml water
poison : water = 100 : 1500 = 1 : 15
Answer: 1 : 15
