Answer:
-4
Step-by-step explanation:
if y = -2 then x = 4
what is y when x = 8

Step-by-step explanation: The correct graph is #6. Cubic Function
Step-by-step explanation:
6|8-y|-15
6|8-10|-15
6|-2|-15
6(2)-15
12-15
-3
What's the question? there isn't enough info to help.
<span>To minimize the perimeter you should always have a square.
sqrt(289) = 17
The dimensions should be 17 X 17
To see , try starting at length 1, and gradually increase the length.
The height decreases at a faster rate than the length increases, up until you reach a square.
Or if you want to use algebra, Say the width is 17-x
Then the length is 289/(17-x)
Now, this is bigger than 17+x, as shown here:
289/(17-x) > 17+x
289 > 289 - x^2
which is true.
so the perimeter would be bigger than 2 * (17- x + 17 + x) = 2 * (2 * 17) = 4 * 17
Again, the dimensions should be a square. 17 X 17.</span>
