C 20 yards
D 10 yards
To convert feet to yards, divide by 3. Therefore, Katy's 120-foot driveway is 40 yards long. The answer is B. 40 yards.
The question asks for the length of Katy's driveway in yards. To convert feet to yards, we use the conversion factor that 1 yard is equal to 3 feet. So, to find the length of the driveway in yards, we divide the total length in feet by the number of feet per yard.
Given that Katy's driveway is 120 feet long:
Therefore, Katy's driveway is 40 yards long.
So the answer is B. 40 yards.

The domain of a function is the set of all possible input values (x). In terms of a real-world scenario where 'y' is a total cost or value, the domain refers to the quantities of a product or service (x) that would result in a total cost of $85.
The domain of a function in mathematics is the set of all possible input values (often designated by 'x'). But in the context of your question where y is a function and the total value is $85, it sounds like you could be referring to a real-world scenario where 'y' might represent a total cost or value in dollars. A function in this context might reflect how different quantities or 'x' values result in a certain cost or 'y' value.
For instance, if you're selling a product for $17 each and you want to know how many you would sell to reach a total of $85, the domain would be all possible amounts of units you could sell (0, 1, 2, 3, etc.). In this case, 5 units would yield a 'y' value of $85, since 5*$17 equals $85. So, the domain would include the number 5, along with any other positive integers up to the point where 'y' total value (the range) doesn't exceed $85.

Answer: OPTION C
Step-by-step explanation:
To solve the exercise shown in the image attached, you need to subtract the functions f(x) and g(x).
Keeping the above on mind, you have:
You must distribute the negative sign and then you must add the like terms, therefore, you obtain:
Answer:
Choice c is correct.
Step-by-step explanation:
We have given two functions:
f(x) = (2x²+ 2)
g(x) = (x²-1)
We have to find (f-g)(x).
(f-g)(x) = ( 2x²+ 2) - ( x²-1)
(f-g)(x) = 2x² + 2 - x²+1
(f-g)(x) = x²+3 is the correct answer.
