The answer I believe is c
(7x^3 – 4x^2) + (2x^3 – 4x^2)
Add 2x^3 to 7x^3
(9x^3 - 4x^2) + (-4x^2)
Add -4x^2 to -4x^2. This would be the same as subtracting 4x^2 from -4x^2
Final Answer: 9x^3 - 8x^2
*The answer cannot be broken down anymore. It's in it's simplest form.
Using a graphing tool, we can see that the whole range of the function
is <span>y</span><span> ∈ [0,∞)
Now, in the interval
</span>
{x | –8 < x < 8}.
The range is
y<span>
∈ [0 ; 6.708) </span>
Answer: Total revenue would be $2400.
Step-by-step explanation:
Since we have given that
Number of units sold = 150
Total revenue = $ 1800
If the number of units = 200
Let the total revenue be 'x'.
Since there is direct variation.
According to question, we get that

Hence, total revenue would be $2400.
