Answer:
Step-by-step explanation:
The expression is
(1/6+2 2/3)x(1 1/4-1/2)
Looking at the first parenthesis, (1/6 + 2 2/3), 1/6 is a proper fraction while 2 2/3 is a mixed fraction. We would convert 2 2/3 to improper fraction. It becomes 8/3. The first parenthesis becomes (1/6 + 8/3). The LCM is 6 so it becomes
(1 + 16)/6 = 17/6
Looking at the second parenthesis, (1 1/4 - 1/2), 1/2 is a proper fraction while 1 1/4 is a mixed fraction. We would convert 1 1/4 to improper fraction. It becomes 5/4. The second parenthesis becomes (5/4 - 1/2). The LCM is 4 so it becomes
(5 - 2)/4 = 3/4
The expression becomes
17/6 × 3/4 = 17/8 = 2 1/8
Answer:
f−1(f(x)) = f(f−1(x)) = x
Step-by-step explanation:
Follow this simple example using the function f(x) = x + 2
f(x) = x + 2
NOw we find the inverse function f^(1)(x).
y = x + 2
x = y + 2
y = x - 2
f^(-1)(x) = x - 2
The inverse function is f^(-1)(x) = x - 2
Now we do the two compositions of functions:
f^(-1)(f(x)) = x + 2 - 2 = x
f(f^(-1)(x)) = x - 2 + 2 = x
Both are equal to x.
Answer: f−1(f(x)) = f(f−1(x)) = x
Answer:
8.3
Step-by-step explanation:
<u>do whats in the brackets first.</u>
13-17-1.3= -5.3
<u>rewrite the equation</u>
3-7+2-[-5.3]+5
3-7+2= -2
<u>rewrite the equation</u>
-2-[-5.3]+5
when 2 negative signs are together u change it to a positive sign.
<u>rewrite the equation</u>
-2+5.3+5
-2+5.3= 3.3
<u>rewrite the equation</u>
3.3+5=8.3
