9880 different possibilities are there in Sally's new combination option second 9880 is correct.
<h3>What is permutation and combination?</h3>
A permutation is the number of different ways a set can be organized; order matters in permutations, but not in combinations.
We have:
Total unique numbers consists in a Sally locker = 3
From the digits 0 to 39
Total numbers = 40
Apply combination formula:
= C(40, 3)
= 40!/(3!37!)
= 9880
Thus, 9880 different possibilities are there in Sally's new combination option second 9880 is correct.

Vertical angle are always congruent
To find the slope between the points, you would go through this process
(-1-6)/(4-0)
And we get
(-7)/4
Aka
-(7/4) which is our slope
Answer:
Slope-intercept form is
y = mx + b
We want to get the y by itself on one side of the equation.
0 = 18x + 6y – 2
First let's subtract 6y from both sides.
-6y = 18x – 2
Next let's divide both sides by -6.
y = (18 / -6)x - (2 / -6)
y = -3x + 1/3
...The last instructions are kind of confusing to me, but I think that is the answer you're after. :)
Divide 180 by 5 to get A-36
