This is the symmetric property, for you divide 9 to both sides to get x, instead of adding (addition property of equality)
So symmetric property should be your answer
Hope this helps
The solution depends on the value of
. To make things simple, assume
. The homogeneous part of the equation is
and has characteristic equation
which admits the characteristic solution
.
For the solution to the nonhomogeneous equation, a reasonable guess for the particular solution might be
. Then
So you have
This means
and so the general solution would be
Answer:
C
Step-by-step explanation:
Using the rule of radicals
× ⇔
Simplifying each radical before combining them.
=
= × = 3
-----------------------------------------------------------------------------
=
= × = 5
---------------------------------------------------------------------------
Hence
2(3) - 3(5
= 6 - 15
= - 9 → C
Answer:
The number is 3
Step-by-step explanation:
Hi,
4 ( 3 + 5x) = 72
12 + 20x = 72
20x = 60
x = 3
Hope this helps :)
