7(x+2)= 7x + 14
7x + 14 = 7x + 14
4F because when you go through the sequence that is what you get
Answer:
The answer to your question is: y = -54 / 11
Step-by-step explanation:
Data
A (3, 0)
B (12, -9)
r = 6/5
Formula
y = 
y = 
y = 
y = -54/11
There aren't any functions listed to choose from, but it should look something like the following:
E= total earnings that day
h= # hours worked that day
n= # people served that day
E= 7h + 5n
substitute 6 hours in for h
E= 7(6) + 5n
E= 42 + 5n OR E= 5n + 42
Hope this helps! :)
D
using the double - angle identity
cos (2A) = cos² A - sin² A = 2cos² A - 1 = 1 - 2sin² A
the right side = 1 - 2sin² (112.5° ) with A = 22.5°
hence 2A = 2 × 22.5° = 45°
thus cos 45° = 1 - 2sin² ( 22.5°)
