Answer:
12
Step-by-step explanation:
Answer:
x = 2
Step-by-step explanation:
The sum of the 3 angles in the triangle = 180°
Sum the 3 angles and equate to 180
6x + 15 + 90 + 63 = 180
6x + 168 = 180 ( subtract 168 from both sides )
6x = 12 ( divide both sides by 6 )
x = 2
Answer:
d
Step-by-step explanation:
Answer:
Step-by-step explanation:
Let x be the price increase.
<u>Then the current price is: </u>
<u>Then the number of passengers is:</u>
<u>Then the revenue: </u>
- Revenue = Price * Number of Passengers
- R = (50 + x)(8000 − 100x) =
- - 100x² + 3000x+ 400000
This is a quadratic relationship. Maximum point is obtained at vertex.
<u>Vertex is determined by x = - b/2a, find the value of x:</u>
- x = - 3000 / (-2*100) = 15
<u>The maximum revenue is:</u>
- R = (50 + 15)(8000 − 100 * 15) = 424500
