Answer:

y = 160 - x

Step-by-step explanation:

Given :

Maximum text character = 160

x = number of typed characters

y = Number of characters left or unused characters

Unused characters = 160 at the start of a fresh message page, which reduced as characters are being typed.

Hence,

Unused characters = (maximum characters - number of typed characters)

y = 160 - x

HELP PLS:

Answer:

Bruce's function:

\displaystyle y=\frac{1}{4}x

Felicia's function:

\displaystyle y=\frac{1}{9}x

<em>Bruce's tiles cover more area</em>

Step-by-step explanation:

<u>Functions </u>

We need to compare the area covered by tile of both Bruce and Felicia. We are required to find the function y, the area covered by the number of tiles he used, x.

We know the tiles used by Bruce cover 1/4 of a square foot, this is written as:

\displaystyle y=\frac{1}{4}x

To find the function for Felicia, we must use the data provided in the table

For example,  

For x=9 tiles, y=1 sq ft

For x=18 tiles, y=2 sq ft

If we set

\displaystyle y=kx

We can find the value of k

\displaystyle 1=9k

\displaystyle k=\frac{1}{9}

Thus

\displaystyle y=\frac{1}{9}x

Testing the constructed function with x=18 and x=27

\displaystyle y=\frac{1}{9}18=2

\displaystyle y=\frac{1}{9}27=3

The function is complete and accurate.

Comparing both functions we see that Bruce's tiles cover more area because

\displaystyle \frac{1}{4}>\frac{1}{9}
