Answer:
(B) the first box
..................................
Just type it into the graphing calculator, but reorder and solve for y first.
x + y = 9
y = 9 - x
y = x^2
In the graphing calculator,
Y1 = 9 - x,
Y2 = x^2
If you don't have a graphing calculator try desmos.

Answer:
2l + 2w = 96 ..... eqn1
lw = 504 ...... eqn2
Step-by-step explanation:
To model this case where we have two unknowns l and w, we need two equations.
Firstly, the perimeter of a rectangle is given by
2l + 2w = p
Where l,w and p are length, width and perimeter of the rectangle respectively.
Hence,
2l + 2w = 96 ... eqn1
Secondly, the area of a rectangle is given by
Length × width = Area
Hence,
l × w = 504
lw = 504 ... eqn2
With these two equations the solutions to the length and width of the rectangular pool can be derived.
