Answer:
The expression 
represents the number 
rewritten in a+bi form.
Step-by-step explanation:
The value of 
is ![i=\sqrt{-1}[tex] or [tex]i^{2}=-1[\tex].Now [tex]i^{4}](https://tex.z-dn.net/?f=i%3D%5Csqrt%7B-1%7D%5Btex%5D%20or%20%5Btex%5Di%5E%7B2%7D%3D-1%5B%5Ctex%5D.%3C%2Fstrong%3E%3C%2Fp%3E%3Cp%3E%3Cstrong%3E%3C%2Fstrong%3E%3C%2Fp%3E%3Cp%3ENow%20%5Btex%5Di%5E%7B4%7D)
in term of ![i^{2}[\tex] can be written as, [tex]i^{4}=i^{2}\times i^{2}](https://tex.z-dn.net/?f=i%5E%7B2%7D%5B%5Ctex%5D%20can%20be%20written%20as%2C%20%3C%2Fp%3E%3Cp%3E%5Btex%5Di%5E%7B4%7D%3Di%5E%7B2%7D%5Ctimes%20i%5E%7B2%7D)
Substituting the value,
Product of two negative numbers is always positive.
Now 
in term of ![i^{2}[\tex] can be written as, [tex]i^{3}=i^{2}\times i](https://tex.z-dn.net/?f=i%5E%7B2%7D%5B%5Ctex%5D%20can%20be%20written%20as%2C%20%3C%2Fp%3E%3Cp%3E%5Btex%5Di%5E%7B3%7D%3Di%5E%7B2%7D%5Ctimes%20i)
Substituting the value,
Product of one negative and one positive numbers is always negative.
Now 
can be written as follows,
Applying radical multiplication rule,
Now, 
and 
Now substituting the above values in given expression,
Simplifying,
Collecting similar terms,
Combining similar terms,
The above expression is in the form of a+bi which is the required expression.
Hence, option number 4 is correct.

Answer:
x=-6
y=4
Step-by-step explanation:
x=-y-2 x=-y-2 x=-y-2 x=-y-2 x=-y-2 x=-4-2 x=-6
0.5x+y = 1 0.5(-y-2)+y=1 -0.5y-1+y=1 -y-2+2y=2 y=4 y=4 y=4
Answer: no solution
Hope this helps and good luck :)
Step-by-step explanation:
Answer:
Perpendicular would be -7
Parallel would be 7
Because m = slope and the m is connected to the x (mx)
