We can set it up like this:
This states that Sam can drive 192 miles in 4 hours and 2220 miles in x hours. To solve, we can use cross-multiplication:
It will take Sam 46.25 hours to drive the whole trip, or 46 hours and 15 minutes.
If you mean 4 / (11/8)
= 4 * 8/11
= 32/11
= 2 10/11
= 2.909
With
the singular ODE can be written as
The first term of the second series admits the indicial equation. When
, we have
Factoring reveals two distinct roots at
(in your case, swap

Next, shift the index of the first sum so that it starts at
by replacing
, then consolidate the sums to get
Setting
, we then have this as
However I don't see the connection to the given answer... It seems some information is missing, specifically about how the coefficients
are related.
Answer:
x= 2/3 -1/3y or x= -1/3y + 2/3
Step-by-step explanation:
3x + y= 2 (subtract the y to get 3x by itself)
3x= 2-y (divide both sides by 3 to get x by itself)
x= 2/3 - 1/3y
