Answer:
B, an = 4n - 9
Step-by-step explanation:
The sequence is for every time the exponent on a goes up one, the number that it equals to goes up by 4. So to find the nth term, we at 4 to n. I hope this helped! :)
Answer:
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
3/5 of 180 is 108
180-108=72
she would have 72$ left
The equation of a line is:
y-yo=m(x-xo)
Where (xo,yo)=(9,3) and m is the slope.
The slope of a line which is parallel to another line is the same; the slope of the line y=6x-4 is 6, then:
y-3=6(x-9)
y-3=6x-54
y=6x-51
