X = [-b±√b²-4ac]/2a
x= [-6±√{6² -4×1×15} /2×1
x= [-6±√(36- 60)]/2
x= [-6±√-24]/2
x= [-6± í2√6] /2
x = -3±2√6ì
x= -3+2√6ì or x= -3-2√6ì

where ì= √-1

lara [203]

Answer:

12

Step-by-step explanation:

y =  - x {}^{2}  + bx + 10 \\ y =  - (x {}^{2}  - bx - 10) \\ y =  -( (x -  \frac{b}{2} ) {}^{2}  -  \frac{b {}^{2} }{4}  - 10) \\ y =  - (x -  \frac{b}{2} ) {}^{2}  + 10 +  \frac{b {}^{2} }{4}  \\  \\ therefore \:  \frac{b}{2}  = 6 \\ b = 12

gizmo_the_mogwai [7]
To create a table like that, you can have two columns. One labeled "Number of People" and the other "Price in Dollars." Since each ticket costs $9.50, the cost for one person must also be $9.50. For two people it would be $19.00 (9.50×2), and so on. The cost of the tickets are proportional to the amount of people. This is because the tickets sell at a constant rate, also know as the constant of proportionality, which in this case is 9.50.
