Step-by-step explanation:
Answer:
y = 10x - 2
Step-by-step explanation:
From the table attached,
Let the equation of a line passing through two points
and
is,
y = mx + b
Here, m = slope of the line
b = y-intercept
Since, m = ![\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
Slope of the line passing through (0, -2) and (1, 8) will be,
m = ![\frac{8+2}{1-0}](https://tex.z-dn.net/?f=%5Cfrac%7B8%2B2%7D%7B1-0%7D)
m = 10
y-intercept 'b' = -2 [Output value at x = 0]
Therefore, equation of the line will be,
y = 10x - 2

Step-by-step explanation:
Answer:
110 liters of water
Step-by-step explanation:
Let
x ----> liters of water
f(x) ----> the percent of the sat in the new mixture
we have
![f(x)=\frac{1.2}{x+10}](https://tex.z-dn.net/?f=f%28x%29%3D%5Cfrac%7B1.2%7D%7Bx%2B10%7D)
For ![f(x)=1\%=1/100=0.01](https://tex.z-dn.net/?f=f%28x%29%3D1%5C%25%3D1%2F100%3D0.01)
substitute in the equation
![0.01=\frac{1.2}{x+10}](https://tex.z-dn.net/?f=0.01%3D%5Cfrac%7B1.2%7D%7Bx%2B10%7D)
solve for x
![x+10=\frac{1.2}{0.01}](https://tex.z-dn.net/?f=x%2B10%3D%5Cfrac%7B1.2%7D%7B0.01%7D)
![x+10=120\\x=120-10\\x=110\ L](https://tex.z-dn.net/?f=x%2B10%3D120%5C%5Cx%3D120-10%5C%5Cx%3D110%5C%20L)
