Let's suppose we want to solve

with

. Separating variables and integrating, we get

Leaving the solution in this form, the initial condition gives

This means the solution is

.
Now if we were to write

, then we would have found

so that the solution would have been

.
But these two solutions are the same, since

. So we get the same solution regardless of where we place

, despite getting different values for

.
A la de 15 años le dara 3750 pesos y a la hija de 8 años le dara 2000 pesos
That would be 13.25, 13+1/4
= 13+(1 divided by 4 which is 0.25)
= 13+0.25
Which is 13.25 so your answer is 13.25, good luck hope that helps :D
Answer: (2,-1).
Step-by-step explanation:
The given system of equations is


For
, table of values is
x : 0 1 2
y : 2 0.5 -1
For
, table of values is
x : -1 2 5
y : -2 -1 0
Plot these points on a coordinate plane and connect them be straight lines as shown below.
Form the graph it is clear that the lines intersect each other at (2,-1).
Therefore, the solution of given system of equations is (2,-1).
Out of the choices given, the principle is $1,000 and the interest is $550. The correct answer is C.
