Answer:
x=-1
Step-by-step explanation:
The price p based on the equation given is p = 3000 - 0.1x.
<h3>How to express the price?</h3>
The equation given in the question is x = 3000 - 10p. The price(p) will be:
x = 3000 - 10p.
Make p the subject of the formula
x + 10p = 3000
10p = 3000 - x
p = (3000 - x)/10
p = 3000 - 0.1x
The revenue will be price multiplied by quantity. This will be:
= (3000 - 0.1x) × x
= 3000x - 0.1x²
The marginal revenue will be calculated after differentiating. This will be:
= 3000x - 0.1x²
= 3000 - 0.2x
The demand which is the quantity based on the information will be:
3000 - 0.2x = 0
0.2x = 3000
x = 1500

None of the above. The first two are slope-intercept, whereas the third one isn't a form.
Answer:
C
Step-by-step explanation:
New equation: y = -3(2y + 3) - 4
Distribute and simplify: y = -6y - 13
Add 6y: 7y = -13
