1.
1.2 x^4 ( 4 x² + 3 x + 1 ) = 4.8 x^6 + 3.6 x^5 + 1.2 x^4
2.
( 4 x - 3 ) ( 2 x² - 7 x + 1 ) = 8 x³ - 28 x² + 4 x - 6 x² + 21 x - 3 =
= 8 x³ - 34 x² + 25 x - 3
3.
( x² + 4 x - 3 ) ( 2 x² + x + 6 ) =
= 2 x^4 + x³ + 6 x² + 8 x³ + 4 x² + 24 x - 6 x² - 3 x - 18 =
= 2 x^4 + 9 x³ + 4 x² + 21 x - 18

So, we are better off taking 12 tickets for $4.68

Hope this helps!

Help please! What is the function, written as a simplified fraction?

andreyandreev [35.5K]

Answer:

$f(\frac{1}{2} )=\frac{14}{3}$

Step-by-step explanation:

Substitute 1/2 wherever you see x

$f(\frac{1}{2} ) = \frac{-2}{3} (\frac{1}{2}) + 5\\$

= -1/3 +5

= -1+15/3

=14/3

multiply 3 by 2/3 and that cancels 2/3 out. also multiply 3 by your -8

x = -24
