Pls:
the tiles that bruce used were each 1/4 of a square foot in area. the table shows the area covered by felicia’s tiles in terms of the number of tiles used.

number of tiles area covered (sq. ft.)
9 1
18 2
27 3
bruce and felicia want to know whose tiles cover the most area per tile.
part a
write an equation representing the area bruce covered, y, in terms of the number of tiles he used, x.

Bruce's function:

Felicia's function:

Bruce's tiles cover more area

Step-by-step explanation:

Functions

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:

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

We can find the value of k

Thus

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

The function is complete and accurate.

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

choice b is correct

step-by-step explanation:

we have been given the following system of linear inequalities;

we are required to graphically determine the solution to these system of inequalities. using a graphing tool, the solution is as shown in the attachment below;

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
