(x-9) (x+2)=x²+2x-9x-18=x²-7x-18
From the table, for every 6 containers of water, you need 8 containers of red dye. So, for every one container of red dye you need 0.75 containers of water (6/8). Then, multiply that by 100 (since you wanted to know water necessary for 100 containers of red dye). For 100 containers of red dye, you would need 75 containers of water.
Answer:10 question 1/2
Step-by-step explanation:
Answer: 72
We can use ratios
117 inches / 13 inches = 9
The corn cast shadow is 9 times bigger than the example we are given.
9 * 8 = <u><em>72</em></u>
Answer:
y = 4/6x - 4
Step-by-step explanation:
y = mx + b, m = slope and b = y intercept
Rise over run
Rise = +4
Run = +6
This means the slope is 4/6.
The y intercept is at -4.
Now, plug in the numbers for y = mx + b
y = 4/6x - 4
