Area = Length x width.
The area of the wall is 8 x 8 = 64 square feet.
The area of one window is 4 x 5 = 20 square feet.
The area of the 3 windows is 20 x 3 = 60 square feet.
The percentage would be (area of windows / area of wall) x 100
Percentage = 60/64 = 0.9375 x 100 = 93.75% (round answer as needed)
In order to graph this function you need to get axis of simmetry (by dividing the number with the squared x between the other number with the x), the vertex where the function changes its direction and the x and y axes cutting points.

Term Definition
Linear regression line The line that goes through a set of points either exactly or approximately.
Difference The result of a subtraction operation is called a difference.
Answer:
A. |x| = 3 C. |-x| =3 E. -|x| = -3
Step-by-step explanation:
a. take away neg in bars, equal pos 3
c. doesn't affect # if neg is inside absolute value bars
E. negative is OUTSIDE the abs val bars, changing it from a pos to neg
first off let's notice that hmmm the vertex is above the point (3,-3), so if we "assume" is a vertical parabola, then it'd be opening downwards.... anyhow that said, let's plug in those values.
