Step-by-step explanation:
Given
$1000 for 9 days
$750 for 10 days
$850 for 4 days
$900 for other days
Required
Compute the daily average
First, we need to compute the number of days her balance is $900
Assuming the billing cycle is 30 days;



The Average is then calculates using:

<em> --- Approximated</em>
NO IM LATE IM SO SORRY IT B
different between A and B
=30-(-30)
=60
position of C from A or B
=(60÷3)×2
=40
possible value of c
=-30+40
=10
possible value of c
=30-40
=-10
(x - 2)² + (y - 6)² = 4
You can be certain about one thing just by looking at the equation (2, 6) is the center, so, obviously the circle isnt going through this point
Since the radius is 2 if we don't move from y = 6 we have points in (0, 6) and (4, 6)
So alternative b.
To be more certain just subs the point in the x and y, if its equal, it pass through
(x - 2)² + (y - 6)² = 4
To point (4, 6)
(4 - 2)² + (6 - 6)² = 4
(2²) + 0² = 4
4 = 4
Thats right
