Answer:

p(4) = $10.69

p(14) = $20.79

p(14) - p(4) = $10.10

p( 14) - p(4)/14-4, and interpret this result

$1.01 This means that during this interval of 10 years, ticket prices increased, on average, $1.01 a year.

Step-by-step explanation:

The average ticket price for a baseball game, in p years after 1991, can be modeled by the following equation:

p(x) = 0.03x^{2} + 0.47x + 8.33

Find p(4).

p(4) = 0.03*4^{2} + 0.47*4 + 8.33 = 10.69

Find p(14).

p(4) = 0.03*14^{2} + 0.47*14 + 8.33 = 20.79

Find p( 14) - p(4).

20.79 - 10.69 = 10.10

Find p( 14) - p(4)/14-4, and interpret this result.

10.10/10 = 1.01.

This is the yearly average rate that the ticket price changed during this interval. This means that during this interval of 10 years, ticket prices increased, on average, $1.01 a year.

Answer:

x = ± 7

Step-by-step explanation:

Given

(2x - 1)(3x + 2) = x + 292 ← expand left side using FOIL

6x² + x - 2 = x + 292 ( subtract x from both sides )

6x² - 2 = 292 ( add 2 to both sides )

6x² = 294 ( divide both sides by 6 )

x² = 49 ( take the square root of both sides )

x = ± 7

That is x = - 7, x = 7
