Answer:
For answer a,
the equation is -1 - 5
this equals -6
From -1 to -6 is 5
A.) The difference is 5
For answer b,
the equation is -7 - (-3)
There are two minus signs by the -3 so that means to turn those two signs into a plus sign
- 7 + 3
Start at -7 and move to the right 3
You will end up at -4
B.) The difference is 3

Answer:
15 students per month
Step-by-step explanation:
The rate of change is calculated as
![\frac{f(b)-f(a)}{b-a}](https://tex.z-dn.net/?f=%5Cfrac%7Bf%28b%29-f%28a%29%7D%7Bb-a%7D)
f(b) = 95 ← number of students in October
f(a) = 65 ← number of students in August
b - a = 2 ← difference in months
Thus
rate of change =
=
= 15
The sum of angles in the triangle = 180
