Answer:
the graph is attached below
Step-by-step explanation:

LEts make a table to get the coordinates
we need to select integers between -3 and 3
x y=x^2 - 2
-2 y=(-2)^2-2=2 (-2,2)
0 y= (0)^2 - 2= -2 (0,-2)
2 y=(2)^2-2 = 2 (2,2)
Now we use the table for graphing the given equation
The graph is attached below
Using the Pythagorean theorem:
WY =√(5^2 + 12^2)
WY = √(25 +144)
WY = √169
WY = 13 mm
Answer:
see explanation
Step-by-step explanation:
Since it is a balance then both sides are the same, that is equal.
The 4 weights represented by circles can be written as 4w, then
4w = 25 ← equation representing the situation
Divide both sides by 4 to find w
w = 25 ÷ 4 = 6.25 ← the weight of 1 circle
