If you slowly increase the strength of an electric current flowing through the wire, you would expect the magnet to become stronger. The correct option among all the options that are given in the question is the first option or option "a". The magnetic field around the wire becomes stronger. I hope it helps you.
Answer:
The statement is true is for any 
.
Step-by-step explanation:
First, we check the identity for 
:
The statement is true for .
Then, we have to check that identity is true for 
, under the assumption that 
is true:

Therefore, the statement is true for any .
3x - 4y = 7
-(3x + 2y = -5)
= 0 - 6y = 12
-6y = 12
y = -2
The resulting equation would be y = -2.
