Answer:
-3x^2+100x-1500
Step-by-step explanation:
Create an equation for the total cost.
1500+200x
1500 is the fixed cost, plus the additional 200 it costs to create a scooter.
Then you need to subtract that from the revenue, which is provided in a function. 300x-3x^2
[300x-3x^2] - [1500+200x]
Solve.
100x - 3x^2 -1500
Write in standard form.
-3x^2+100x-1500
9514 1404 393
Answer:
D. x = 5
Step-by-step explanation:
Add x+3 to both sides and simplify.
9x -3 -8x +(x +3) = 7 -x +(x +3)
2x = 10 . . . . . simplify
x = 5 . . . . . . . divide by 2
__
As you can see, the expression we chose to add (x+3) is the one that results in variable terms being separated from constant terms after simplification.
