Answer:
B
Step-by-step explanation:
So we have the function:
To find the inverse, flip f(x) and x, change f(x) to f⁻¹(x), and solve for it. Thus:
Subtract 32 from both sides:
Multiply both sides by 5/9. The right side will cancel. Thus:
Our answer is B.
And we're done!

Answer:
b = 2/3
Step-by-step explanation:
Solve for b:
1 = 3 b - 1
1 = 3 b - 1 is equivalent to 3 b - 1 = 1:
3 b - 1 = 1
Add 1 to both sides:
3 b + (1 - 1) = 1 + 1
1 - 1 = 0:
3 b = 1 + 1
1 + 1 = 2:
3 b = 2
Divide both sides of 3 b = 2 by 3:
(3 b)/3 = 2/3
3/3 = 1:
Answer: b = 2/3

Answer:
Odd is the answer.
Step-by-step explanation:
An even number can be written in the form 2x, where x is an integer.
An odd number can be written in the form 2x + 1, where x is an integer.
So two odd numbers can be represented by 2a +1 and 2b +1, the product would be:
(2a + 1)(2b +1) = 4ab + 2a + 2b + 1 = which can be written as 2(2ab + a +b) + 1, but 2ab +a + b represents some integer, so 2ab + a + b = x.
So (2a + 1)(2b + 1) = 2(2ab + a + b ) + 1 = 2x +1 which is odd.
