F ( x ) = x³ + 3 x² - 9 x - 8We have to derive this function:f ` ( x ) = 3 x² + 6 x - 93 x² + 6 x - 9 = 0   /:3x² + 2 x - 3 = 0x² + 3 x - x - 3 = 0x ( x + 3 ) - 1 · ( x + 3 ) = 0( x + 3 ) · ( x - 1 ) = 0x1 = - 3,  x2 = 1f max = f ( - 3 ) = - 27 + 27 +27 - 8 = 19f min = f ( 1 ) = 1 + 3 - 9 - 8 = - 13Answer:B ) The relative maximum is at ( - 3 , 19 ) and the relative minimum is at ( 1 , - 13 ).

Simplify -9(1-10n) - 2(3n+9)
agasfer [191]

Answer:

3 (28 n - 9)

Step-by-step explanation:

Simplify the following:

-9 (1 - 10 n) - 2 (3 n + 9)

-9 (1 - 10 n) = 90 n - 9:

90 n - 9 - 2 (3 n + 9)

-2 (3 n + 9) = -6 n - 18:

90 n + -6 n - 18 - 9

Grouping like terms, 90 n - 6 n - 18 - 9 = (90 n - 6 n) + (-9 - 18):

(90 n - 6 n) + (-9 - 18)

90 n - 6 n = 84 n:

84 n + (-9 - 18)

-9 - 18 = -27:

84 n + -27

Factor 3 out of 84 n - 27:

Answer: 3 (28 n - 9)
