Answer:
Step-by-step explanation:
The center of the circle is the midpoint of the two end points of the diameter.
Formula
Center = (x2 + x1)/2 , (y2 + y1)/2
Givens
x2 = 4
x1 = - 10
y2 = 6
y1 = - 2
Solution
Center = (4 - 10)/2, (6 - 2)/2
Center = -6/2 , 4/2
Center = - 3 , 2
So far what you have is
(x+3)^2 + (y - 2)^2 = r^2
Now you have to find the radius.
You can use either of the endpoints to find the radius.
find the distance from (4,6) to (-3,2)
r^2 = ( (x2 - x1)^2 + (y2 - y1)^2 )
x2 = 4
x1 = -3
y2 = 6
y1 = 2
r^2 = ( (4 - -3)^2 + (6 - 2)^2 )
r^2 = ( (7)^2 + 4^2)
r^2 = ( 49 + 16)
r^2 = 65
Ultimate formula is
(x+3)^2 + (y - 2)^2 = 65
The radius is √65 = 8.06
The answerrRRRRRRRRRRRRRRRRRRRR is A

Answer:
The answer is £20
Step-by-step explanation:
Since the game is half-priced, we just have to divide the original price by 2.
£40/2 = £20
Answer:
Option D
Step-by-step explanation:
We have the following variable definitions:
sofas: x
pillows: y
Pillows come in pairs so we have 2y pillows
The total order for all the possible combinations is:
The wholesaler requires a minimum of 4 items in each order from its retail customers. This means the retailers can order 4 or more.
Therefore the inequality is:
To graph this inequality, we graph the corresponding linear equation, 
with a solid line and shade above.
The correct choice is D
