Answer:
All Real Numbers
Step-by-step explanation:
Assuming that V is just a constant, you can re-write the equation as:
y = Vx-6.
This is a linear equation. Linear equations have a domain and range that both are "all real numbers".
Answer:
A
Step-by-step explanation:
We are given two functions:

And we want to find:

Thus:

We can factor the denominator of the first term:

In order to add the two terms, we must have a common denominator. To achieve this, we can multiply to second term by (x - 4). Therefore:

Multiply:

Combine:

Simplify:

We can expand the denominator:

Therefore, our answer is A.
Answer:
1.32 kg
Step-by-step explanation:
Given a fraction of the market goods, we can find the remaining fraction by subtracting the given fraction from 1.
The fraction of the goods the farmer sells that is pears will be ...
(apples +pears) = (apples) +(pears)
pears = (apples +pears) -(apples)
pears = 1 - 4/5 = 1/5 . . . . . of the total goods
One-fifth of the goods sold will have a weight of ...
(1/5) × (6.6 kg) = 1.32 kg
The farmer sold 1.32 kg of pears at the market.
