Answer:

9x² - 8x - 6 = 0

Step-by-step explanation:

11 - 4x = (3x - 2)² + 1

FOIL the (3x - 2)².

(3x - 2)² = (3x - 2)(3x - 2) = 9x² - 12x + 4

Rewrite the Equation.

11 - 4x = 9x² - 12x + 4 + 1

Move all to one side and combine like terms.

9x² - 8x - 6 = 0

Answer:

B

Step-by-step explanation:

Given

11 - 4x = (3x - 2)² + 1 ← expand the squared factor using FOIL

11 - 4x = 9x² - 12x + 4 + 1, that is

11 - 4x = 9x² - 12x + 5 ( add 4x to both sides )

11 = 9x² - 8x + 5 ( subtract 11 from both sides )

0 = 9x² - 8x - 6 or

9x² - 8x - 6 = 0 → B

ddd [48]

The two person will pay the same amount of money when they both watch 9 hockey games.

<h3>How to find the equation and use it to find cost?</h3>

A hockey season ticket holder pays $99.00 for her tickets plus $3.00 for a program for each game. Therefore,

y = 99 + 3x

where

y = total cost

x = number of game

A second person pays $14.00 for a ticket to every game but doesn't buy programs. Therefore,

y = 14x

The number of games they will have the same amount is as follows:

99 + 3x = 14x

99  = 14x - 3x

99 = 11x

x = 99 / 11

x = 9

Therefore, they will have the same amount when they watch 9 games.

H(x)=1/8x^3-x^2<br><br> Over which interval does h have a positive average rate of change?
lara31 [8.8K]

Answer:

(-\infty,0)\cup(\frac{16}{3},\infty)\\That \ is x\frac{16}{3}

Step-by-step explanation:

h(x)=\frac{1}{8}x^{3} -x^{2} \\\\Differentiate \ h(x) \ with \  respect \ to \ x\\h'(x)=\frac{3}{8}x^{2} -2x

For positive rate of change h'(x)>0

\frac{3}{8} x^{2} -2x>0\\x(\frac{3}{8}x-2)>0\\\\ When \ x0 \ (multiplication \ of \ two \ positives \ is \ positive)\\\\h'(x)>0 \ when \ x\frac{16}{3} \\\\
