Classwork:
Given
and
, we have
(1) 
Using the composition found in (1), we have
(2) 
(3) 
Using the composition found in (3),
(4) 
Homework:
Now if
, we would have
(1) 
For (2), we could explicitly find
then evaluate it at <em>x</em> = -1 like we did in the classwork section, but we don't need to.
(2) 
(3) We can demonstrate that both methods work here:
• by using the result from (1),

• by evaluating the inner function at <em>x</em> = 2 first,

<u>0.8 / 9.2 = x + 0.2</u>
Perform the division on the left side: 0.08696 = x + 0.2
Subtract 0.2 from each side: <em>-0.113 = x</em> (rounded)
Answer:
6
Step-by-step explanation:
we will calculate the prime factors( gcd) of the numbers by matching the biggest comman factor of 24 or 30
Answer:
-3
Step-by-step explanation:
-15/5 is equivalent to -3, so wherever on your number line "-3" is, circle that
Green is 50 and the blue is 30 degrees
