Answer:
-108
Step-by-step explanation:
About the easiest way to do this for small values of n is to compute each of the terms using the given recurrence relation.
_____
<em>Alternate solution</em>
You recognize that the recurrence relation describes a geometric sequence with a first term of 4 and a common ratio of -3. The n-th term of a geometric sequence is ...
Then the 4th term will be ...
Answer:the two equations that model the situation are
x + y = 48
3x + 2y = 15
Step-by-step explanation:
Let x represent the total number of hours that Derek worked.
Let y represent the total number of hours that Donnie worked.
Derek and Donnie mow 15 lawns over two 2 days. There are 24 hours in a day. Therefore, the number of hours in 2 days would be 2 × 24 = 48 hours. Therefore
x + y = 48 - - - - - - - - - -1
If Derek mows 3 lawns per hour and Donnie mows 2 lawns per hour, it means that
3x + 2y = 15 - - - - - - - - - 2
Answer: g < 1 3/5
Step-by-step explanation:
first, i removed the parentheses.
19 > 2g + 15.8
then, i moved the terms.
-2g > 15.8 - 19
the, i calculated that.
-2g > -3.2
finally, i divided both sides.
g < 1.6
the alternative form is g < 1 3/5
(basically, the second answer)
