Answer:
x^2 +9x +1
Step-by-step explanation:
(5x-2+3x^2)+(4x+3)
Writing in decreasing order so we can combine like terms
3x^2 +5x+4x-2+3
Add and subtract like terms
3x^2 +9x +1
The answer is 999999.99995
Step-by-step explanation:
16 arrangement can be done
Answer:
Step-by-step explanation:
make common denominators
2/4n - 1/4n + 2/6a + 3/6a
add common equations
1/4n + 5/6a
d) d = 2.5t, continuous
Explanation:
Jeff is traveling at the same pace, so he is moving at constant speed: its motion is a uniform motion, so the distance he covers (d) as a function of the time (t) is expressed by the law
(1)
where v is Jeff's speed.
We can find the speed from the initial data:
t = 2 hours
d = 5 miles
so, the speed is given by the ratio between the distance and the time
Therefore, equation (1) becomes
and the graph is continuous, because t can have any real value.
