Answer: 8.2 mm
Step-by-step explanation:

Answer:
B
Step-by-step explanation:
let y = f(x) and rearrange making x the subject, that is
y = x - 3 ( add 3 to both sides )
y + 3 = x
change y back into terms of x, then
(x) = x + 3 → B
5a - 5 = 10a
-5 = 5a
a = -1
Answer:
gets smaller.
Step-by-step explanation:
Quick Answer
To give you a short quick answer, the supplement is going to have to decrease or get smaller.
Example
Suppose the acute angle is 10 (anything under 90 will do).
Then the supplement is going to be 180 - 10 = 170
Now suppose the acute angle increase to 50 degrees.
That means the supplement will go from 180 - 50 = 130
Conclusion
As the acute angle gets bigger, the supplement gets smaller. This is an important idea to get clear. Bigger and Smaller or More or Less can be ugly little words, so anytime you come across them, pay attention. It will make your life in science so much easier.
Answer:
All are valid
Step-by-step explanation:
Px - 43 = -42x + Q (rearrange)
x = (Q+43) / (P + 42) <----Substitute options for P & Q into this equation to see which combination gives exactly 1 solution for x
A) P=42, Q = 42; x = (42+43) / (42+42) = 1.011 (only 1 solution = valid)
B) P=43, Q = -42; x = (-42+43) / (43+42) = 0.012 (only 1 solution = valid)
C) P=-43, Q = -43; x = (-43+43) / (-43+42) = 0 (only 1 solution = valid)
D) P=42, Q = 43; x = (42+43) / (42+42) = 1.023 (only 1 solution = valid)
