Answer:
The answer would be division (B)
Step-by-step explanation:
4x equals the total amount
x equals the cost of one item
Therefore you'd divide total cost by 4 and that would find the cost of one item
8x - 2y = -8
-5x + 2y = -1
3x = -9
x = -3
sorry i dunno i really dont i just need to finish my test lol

Step-by-step explanation:
Answer:
odd function
Explanation:
To determine if a function f(x) is even/odd consider the following.
• If f(x) = f( -x) , then f(x) is even
Even functions are symmetrical about the y-axis.
• If - f(x) = f(-x) , then f(x) is odd
Odd functions have symmetry about the origin.
Test for even function
f(−x)=4(−x)3=−4x3≠f(x)
Since f(x) ≠ f( -x) , then f(x) is not even
Test for odd function
−f(x)=−(4x3)=−4x3=f(−x)
Since - f(x) = f( -x) , then f(x) is odd
graph{4x^3 [-10, 10, -5, 5]}
Given that Rolex buys computer disks at a price of 4 for $5 .
That means cost price of 1 disk = 5/4
Given that Rolex sells them at a price of 3 for $5.
That means selling price of 1 disk = 5/3
Profit on 1 disk = selling price - cost price
Profit on 1 disk 
Profit on 1 disk 
Profit on 1 disk 
Profit on 1 disk 
Now we have to find how many disk to be sold to get the profit $100
so we just divide $100 by profit on 1 disk
Hence final answer is 240 disks.
