Answer:
6x-3.
Step-by-step explanation:
-3(-2x+1) : distribute the -3 to "-2x" and "1."
6x-3: this is the answer.
Answer:
He needs to work 8 hours minimum.
Step-by-step explanation:
9*8 = 72 and he already has 8 dollars saved making it 80. Just enough to get him what he wants. Hope this helped! :)
The objective is to state why the value of
converging alternating seies with terms that are non increasing in magnitude
lie between any two consecutive terms of partial sums.
Let alternating series
<span>Sn = partial sum of the series up to n terms</span>
{S2k} = sequence of partial sum of even terms
{S2k+1} = sequence of partial sum of odd terms
As the magnitude of the terms in the
alternating series are non-increasing in magnitude, sequence {S2k} is bounded
above by S1 and sequence {S2k+1} is bounded by S2. So, l lies between S1 and
S2.
In the similar war, if first two terms of the
series are deleted, then l lies in between S3 and S4 and so on.
Hence, the value of converging alternating
series with terms that are non-increasing in magnitude lies between any two
consecutive terms of partial sums. So, the remainder Rn = S – Sn alternating
sign

4.) 2(x-1)+3= 2x+1
Distribute the 2, multiply the 2 by x and -1.
2*x= 2x (all you need to do is put 2 in front of x)
2*-1= -2
2x-2+3= 2x+1
Combine like terms.
2x+1=2x+1
Subtract one on both sides.
2x=2x
Divide by 2 into both sides.
x=1
We can check this by plugging it in.
2(1-1)+3= 2(1)+1
2(0)+3= 2+1
0+3=3
3=3 <== this works
I hope this helps!
