Heath needs to end up with 10L of solution, 

of which 9L is bleach. So let m = liters of 20% 

solution needed. Then .20m liters of that are bleach. 

He must then add p liters of bleach to make 

a total of 10 L. That is, p + m = 10. So the system is 

m + p = 10, .20m + p = 9. Solving, 

<span>m = 1.25 L 20% solution, and thus p = 8.75 L bleach.</span>

Draw the graph of f(x) = (x − 1)2 − 2. Start by creating a table of ordered pairs for the function. Then plot the points from th
pogonyaev

The attached graph represents the graph of f(x) = (x - 1)^2 - 2

<h3>How to plot the graph?</h3>

The equation is given as:

f(x) = (x - 1)^2 - 2

Next, we set x to -2, -1, 0, 1 and 2.

So, we have:

f(-2) = (-2 - 1)^2 - 2 = 7

f(-1) = (-1 - 1)^2 - 2 = 2

f(0) = (0 - 1)^2 - 2 = -1

f(1) = (1 - 1)^2 - 2 = -2

f(2) = (2 - 1)^2 - 2 = -1

This means that the table of values is

x      f(x)

-2    7

-1    2

0    -1

1     -2

2    -1

Next, we plot the above points and connect them.

See attachment for the graph of f(x) = (x - 1)^2 - 2

The difference between 11.0 and 12.5 is 1.5 and same with 12.5 and 14.0, so 1.5 is what the hair increases by every THREE months but if you want to find PER month, you are going to divide 1.5 by those 3 months to get .5 inches per month, so your slope will be 1/2
