Answer:
The circle is centered at (-8,3) and has a diameter of 20 units
Step-by-step explanation:
we know that
The equation of a circle in center radius form is equal to

where
(h,k) is the center of the circle
r is the radius of the circle
In this problem we have

so
The center is the point (-8,3)
The radius is 
so
The diameter is two times the radius

therefore
The circle is centered at (-8,3) and has a diameter of 20 units
Answer:
A The data is proportional and the unit rate per package is $8 This is because y= 8x
Step-by-step explanation:
/y relationship is no of packages = 1 x/ = total cost to ship = 8 = 8/1 = 16/2 = 24/3 = 32/4 means they are all proportional to 8/1 = 8 y = 8x see graph attached
Answer:
1. y= -1/4x +2
2. y= -2x -1
Step-by-step explanation:
