Answer:
10c + 1200 ≥ 3000, c≥ 180
Step-by-step explanation:
We know that they need at least $3000; meaning, it may be $3000 or more. This leaves us with eliminating the bottom two choices.
We then look at the first two choices. If we were to subtract from 1200, we would not know the total income amount that has been gained. It would also eventually give us negative numbers. We cannot have a negative amount earned. Instead, we would use the 10c+1200 because this would allow us to visualize that it needs to be greater than or equal to 3000
5*9=45
3*9=27
45-27=8
9*2=18
Therfeore the answer is A.
The answer to your question would be 6.25 and the equation you need to solve is: (0.8x+2)/0.01=700.
Hope this helps!
Answer:
The slope of tangent at point (1,-2) is 
.
Step-by-step explanation:
The given equation of ellipse is
Differentiate both sides with respect to x.
Calculate the value of \frac{dy}{dx} at (1,-2).
Therefore the slope of tangent at point (1,-2) is .
Answer:
7x² - 6x - 18
Step-by-step explanation:
7x² - 6(x + 3)
multiply with -6
7x² - 6x - (6 × 3)
evaluate
= <u>7x² - 6x - 18</u>
