6 0

Step-by-step explanation:

This means the price of the book will decrease by 100%-30%=70%

70% decrease in x = 100% of x - 70% of x = 1x - 0.7x = (1 - 0.7)x = 0.3x So 0.3x represents a 70% decrease in x.

Notice that this multiplier .3 is the same as (30% of x).

the answer is 0.3.

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
