Answer:
4,8
Step-by-step explanation:
let the numbers be x and y
x+y=12
x-y=-4
add
2x=12-4=8
x=8/2=4
4+y=12
y=12-4=8
so numbers are 4 and 8
Answer is A
if x+y=5
y= -x+5
2x + (-x+5) =-2
2x -x +5 = -2
x+5 = -2
x=-7
Answer: 8 vertices

Step-by-step explanation:
An insurance company has provided you with a sample of paid claims. The sample includes the following claims: 192, 113, 200, 287, and 225. What are the mean and the variance respectively of this sample rounded to the nearest whole number?
Look at the coordinates. They are both negative. (-5,-1)
Let me plot all the coordinates so you can see:
Joe= (-3,4)
Dan= (1,4)
Roy= (2,-3)
Lee= (-3,-4)
The only person with coordinates that are both negative is Lee.
"C" is the answer. Lee.
I hope this helps!
