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
The precise equation that represents the situation is as follows:
- $19, x ≤ 300
- x > 300,
- f(x) = 19 + 0.39(x - 300)
<h3>How to represent an equation?</h3>
His cell phone plan provides 300 free minutes each month for a flat rate of $19.
let
x = number of minutes used
Therefore,
$19, x ≤ 300
For any minutes over 300, Andrew is charged 0.39 per minute.
Therefore,
if x > 300
f(x) = 19 + 0.39(x - 300)
