Answer:
d = 240 - 44t
Step-by-step explanation:
Distance of the raft to the waterfall
The raft is heading for the waterfall, therefore, the distance between the raft and the waterfall is diminishing.
Waterfall=240 ft from the tunnel
Speed of the raft =44 ft per second
Therefore the equation of a function rule that represent the distance of the raft to the waterfall is:
d = 240 - 44t
Where t=time in seconds
$105.65/5 shirts = $21.13/shirt
Answer:
-2x³ + x² - 3x - 15
Step-by-step explanation:
Simply combine like terms together:
-5x² - 3x - 7 - 2x³ + 6x² - 8
-2x³ + (-5x² + 6x²) - 3x + (-7 - 8)
-2x³ + x² - 3x + (-7 - 8)
-2x³ + x² - 3x - 15
