Answer:
There are no real roots for this equation.
Step-by-step explanation:
The only solution is irrational: x-√(4-8x)=0
I have provided a graph to help you with this problem.
Hope this helps! :)
V3+4v2-5v+3v2+12v-15
v3+7v2+7v-15
30 + (40 × 3) = 150
60 + (30 × 3) = 150
in three months the total cost would he the same.
Answer:
60 seconds
Step-by-step explanation:
Hi!
After she goes forward 5 feet (4 seconds), and the backwards 3 feet (another 4 seconds), the total distance forward she travelled is 2 feet. Then, she moved forward 2 feet in 8 seconds.
Then, as this is repeated, she moves forward 2 feet every 8 seconds. After 7 repetitions she travelled 14 feet, and 56 seconds elapsed. Then she goes forward 5 feet in 4 seconds, and she finaly reaches the end of the hallway
(14 +5 > 15)
So, in 60 seconds she reached the end of the hallway.
If you multiply 1/4 by 2 it would be 2/8 so if you compare 2/8 and 5/8 she bought 3/8 pounds more
