Answer:
x=7
Step-by-step explanation:
This is a vertical line. Vertical lines are of the form x=
The x coordinate is 7
x=7
For f(10) replace x with 10 then solve:
f10) = 10^2 + 1
= 100 +1
= 101
Answer:
There are 1716 ways the three positions can be filled by these applicants.
Step-by-step explanation:
Permutation is the number of arrangement of <em>k</em> items from <em>n</em> distinct items.

For example, permutation can be used to compute the number of ways to arrange 4 mathematics books together when arranging all the 7 books on a shelf.
In this case there are 3 available nursing positions to be filled.
A total of 13 candidates are qualified for all the three positions.
Then the number of ways the 3 positions can be filled by the 13 candidates can be determine using permutation.
Compute the possible number of selections as follows:

Thus, there are 1716 ways the three positions can be filled by these applicants.
X=4
Step-by-step explanation:
Solve for x by moving all terms to the left side
7x+9=13+6x
subtract 6x from both side
7x+9-6x=13
subtract 6x from 7x
x+9=13
subtract 9 from both sides
x=4
