Answer:

=−x2+11x−10

Step-by-step explanation:

Let's simplify step-by-step.

9(x−1)−(x−1)2

Distribute:

=(9)(x)+(9)(−1)+−x2+2x+−1

=9x+−9+−x2+2x+−1

Combine Like Terms:

=9x+−9+−x2+2x+−1

=(−x2)+(9x+2x)+(−9+−1)

=−x2+11x+−10

Find the equation of the line parallel to the line y = 2x + 3 and expect oy in (0; 1)
nignag [31]

Step-by-step explanation:

Any lines that are parallel to each other have the same slope (coefficient of x is the same)

In this case, y = 2x + c.

Since it includes the point (0, 1), the y-intercept is 1 and that is c itself.

Hence, the equation of the parallel line is y = 2x + 1.

denpristay [2]
Total Cost in a day is TC= 90 + 12n. Profit function is P=18n. And the revenue function is R = P-TC = 18n-12n-90 = 6n-90. In a day, bookstore must sell at least 15 books, because of 6n-90=0, in order to make profit.

matrenka [14]

Jenny won the race as she finished the race much more quickly and has greater average speed than Lester.

\sf \boxed{\sf speed:\frac{distance}{time \ taken} }

Jenny: distance/time = 100/15.2 = 6.58 m/s = 6.6 m/s

Lester: distance/time = 100/15.7 = 6.37 m/s = 6.4 m/s
