You usually buy a 16.5-ounce bottle of shampoo. There is a new bottle that says it gives you 30% more free.
Katarina [22]

Answer:

\frac{x-16.5}{16.5}=0.30

Hopefully, this is your desired setup. (I noticed the formula you have to fill in there.)

Have a good day.

Step-by-step explanation:

Hi.

You could use the percent change formula.

Since we know it is a percent increase then we will do new-old instead of old-new:

\frac{\text{new}-\text{old}}{\old}

x is the new amount of shampoo.

16.5 is the original amount (old) of shampoo.

The percent increase is 30%=0.30 .

So we have the following equation:

\frac{x-16.5}{16.5}=0.30

We could have found the equation like this:

16.5+16.5(0.30)=x

Subtract 16.5 on both sides:

16.5(0.30)=x-16.5

Divide both sides by 16.5:

0.30=\frac{x-16.5}{16.5}

By us of symmetric property of equality:

\frac{x-16.5}{16.5}=0.30

This graph shows a portion of an odd function.
damaskus [11]

Answer:

f(x) =

-2

-1

-2

-3

On Edgenuity 2020

Step-by-step explanation:

Got it correct on Edgenuity :)

Or if you would like the longer explanation;

The graph given explained:

On a coordinate plane, a function has four connecting lines. The first line goes from (0, 0) to (2,2), the second line goes from (2, 2) to (3, 1), the third line goes from (3, 1) to (5, 3), and the fourth line is horizontal to the x-axis at 3.

After finding the matching points on the graph using the coordinates on the x axis (on the line), you should get 2, 1, 2, and 3. Then use the odd function which is

f(-x) = -f(x) and insert those numbers in -f(x)

which leads you to the answer above which is

f(x) =

-2

-1

-2

-3

Hopefully this helped !

Sorry I couldn't explain it any better but I did it in a way that I was able to understand how I got my answer ! :)
