Answer:
12
Step-by-step explanation:
4u - 8u = -63 + 15 ( collecting like terms)
-4u = -48
u = 12
The two expressions are both rational numbers- they are ending, whole and have no decimals.
I would guess 61 in my school we only do things like this x4 - 5 x times four minus five so I don’t know if that’s right but that would be my guess if that isn’t right it would be 62 times 2
It can be rounded to 270,000 because 4 is less than half. (4 and below drops it down)
Euler's method uses the recurrence relation

to approximate the value of the solution

to the ODE

.

With a step size of

, there will only be two steps necessary to find the approximate value of

based on the initial point

. See the attached table below for the computation results.
To demonstrate how the table is generated: Since

, you are using

The next point then uses
