$f( \frac{3}{ {x}^{2} - 16 } ) = ({\frac{3}{ {x}^{2} - 16 }})^{2} - 7(\frac{3}{ {x}^{2} - 16 }) + 12 \\ = \frac{9}{ {x}^{4} - 32 {x}^{2} + 256 } - \frac{21}{ {x}^{2} - 16} + 12$

Evgen [1.6K]

Step-by-step explanation:

(48 - 12.80)/2 = $17.6

250/6 ≈ 42 and more

485 - 319 = 166 more people

14.5x + 80 > 500
14.5x > 420
x > 420/14.5
x > 29

1.25x + 3 ≤ 28
1.25x ≤ 25
x ≤ 25/1.25
x ≤ 20 miles

6. This seems a typo... 460 is likely $60

60x + 145 ≤ 625
60x ≤ 625 - 145
60x ≤ 480
x ≤ 480/60
x ≤ 8 days
