Answer:
The domain of f is x > 0.
The range of f is all real numbers.
The domain of the inverse function is all real numbers.
The range of the inverse function is y > 0.
The domain of f is the same as the
range of the inverse function.
The range of f is the same as the
domain of the inverse function.

Answer:
d + 85
Step-by-step explanation:
Look at it like this,
suppose you have 1 DVD, and the mother buys 85 DVDs then you have 1 + 85 = 86 DVDS
or when you have 2 DVDs, then you have 2 + 85 = 87 DVDs afterwards.
notice that you always take the number of DVDs you already have, and add 85 to it.
d is just a number, but you just don't know it yet. you can change d by any number, and you know d+85 is the number of DVDs afterwards
|-4 +5i| = √((-4)² +5²) = √(16+25) = √41
|z| = √41
Answer:
D
Step-by-step explanation:
First you need to distribute the negative to 5,3x and -4 now you have this:
-3.5x+7-5.3x +4 rearrange and combine like terms (matching x's with x's etc.)
-3,5x -5.3x +7+4
-8.8x +11 your final answer there are no more like terms that you can combine.
