Javier and his study group designed a word problem, equation, table, and graph that were all supposed to represent the same info
rmation, as shown below.
Word problem: A movie theater charges $8.00 for teach ticket. What is the total cost, y, for x tickets?
Equation: y= 8x
Table:
X.....Y
5....40
8....64
12...96
13...104
*Graph is shown in photo*
Which piece of information does not represent the same information as the three other parts?
A. Word problem
B. Equation
C. Graph
D. Table

Answer:
area A(w) of the bulletin board as a function of its width, w =[100-w]*w= 100w-
Step-by-step explanation:
- let, the shape of the bulletin board is a rectangle,
- then the perimeter of it = sum of all sides
= 2[length+width] = 2[l+w]
(let l: length, w : width )
- so, 200 = 2[l+w]
100= l+w ( dividing both the sides by 2)
so, l= 100-w
- area = length*width=l*w=[100-w]*w
- therefore,area A(w) of the bulletin board as a function of its width, w =[100-w]*w= 100w-
