Answer:
- 16
Step-by-step explanation:
Average is calculated as
average =
Thus for the given 10 numbers we have
= - 5 ( multiply both sides by 10 )
total = - 50
let the number added be x, then
= - 6 ( multiply both sides by 11 )
total + x = - 66, that is
- 50 + x = - 66 ( add 50 to both sides )
x = - 16
The new number is - 16
The missing options are:
C. In the xy plane, point (20, 5,000) is on the graph y = f(x).
D. In the xy plane, point (5,000,20) is on the graph y = f(x)
Answer:
C. In the xy plane, point (20, 5,000) is on the graph y = f(x).
Step-by-step explanation:
Given
Represent amount with y and weeks with x
So, we have:
x = 20 when y = 5000
Required
Select 2 correct options
A point on a graph can be illustrated using
So, when x = 20 and y = 5000 ----- given
implies that:
We got by substituting 20 for x and 5000 for y

<em>From the list of given options, the above represented of (x,y) is illustrated in option C</em>
Represent (x,y) as a function, we have:
Substitute values for x and y
Reorder
<em></em>
The above is illustrated in option A
<em>Hence, A and C answers the question</em>
