Answer:
see explanation
Step-by-step explanation:
the equation of a circle in standard form is
(x - h)² + (y - k )² = r²
where (h, k ) are the coordinates of the centre and r is the radius
given
x² + y² - 8x + 8y + 23 = 0
collect the x and y terms together and subtract 23 from both sides
x² - 8x + y² + 8y = - 23
using the method of completing the square
add ( half the coefficient of the x / y terms )² to both sides
x² + 2(- 4)x + 16 + y² + 2(4)y + 16 = - 23 + 16 + 16
(x - 4)² + (y + 4)² = 9 ← in standard form
with centre = (4, - 4 ) and r =
= 3
this is shown in graph b

Answer:
The total salary of her is $1066666.66.
Step-by-step explanation:
Given : Allison earns a $40,000 base salary plus a commission equal to 15% of her total sales. If she sold $200,000 worth of goods.
To find : What was her total salary?
Solution :
Let x be the total salary.
Allison earns a $40,000 base salary.
If she sold $200,000 worth of goods.
i.e. the amount is $200,000-$40,000=$160,000
The total salary is given by,
$160,000=15% of x



The total salary of her is $1066666.66.
I got -2 as the slope hope this helps:)
