Answer:
This isn't really an answer,but I used to use an app called "Photomath" it shows you the answer as well as the work.

Answer:
Step-by-step explanation:
y = ax² + bx + c
Plug the points into the equation to get a system of 3 equations with 3 unknowns a, b, and c.
-27 = 4a - 2b + c
-42 = 9a + 3b + c
-12 = a + b + c
(a,b,c) = (-4,1,-9)
y = -4x² + x - 9
Answer
Find out the how many tiles are in each section .
To prove
Let us assume that the number of tiles are in section are be x.
As given
A mosaic at the art museum is divided into 6 sections that each contain about the same number of tiles.
There are 2,889 tiles total in the mosiac .
Than the equation becomes
6 × x = 2889
x = 481.5
Therefore the total number of tiles in each sections are 481.5 .

I might be wrong, but hopefully that helped! :)
Less than 2 = z < 2
Less than or equal to 8 = z ≤ 8
z ≤ 8
z < 2
