Answer:
A.
Step-by-step explanation:
In order to find the cost of the wallpaper per square foot, we must do 700.92 divided by the area of the wallpaper.
Area = length times width
Area of wallpaper = 12*9=108
700.92/108 = 700.92/108 = 6.49
The cost per a square foot is $6.49, so the answer is A.
Hope this helps :)
Answer:

Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + b
where m is the slope and b the y- intercept
Table-1 shows constant increase of X and Y values
Step-by-step explanation:
We are given two tables with X and Y values.
To find which table represent the constant increase of X and Y:
If there is constant increase of X and Y then, X and Y avlues belongs to equation of line.
Also, if three points lies on line then, slope of line made by three points must be same or equal.
Slope of line is given as s=
For table 1:
The values of X and Y form points as A(3,4),B(5,6) and C(7.8)
For A(3,4) and B(5,6)
s=
s=
s=1
For C(7.8) and B(5,6)
s=
s=
s=1
Therefore, Table-1 shows constant increase of X and Y values
For table 2:
The values of X and Y form points as A(1,3),B(2,6) and C(3,10)
For A(1,3) and B(2,6)
s=
s=
s=3
ForC(3,10) and B(5,6)
s=
s=
s=2
Therefore, Table-1 does not shows constant increase of X and Y values
I’m going to go with A, because it seems they all meets the definition of congruent
