It's -18.
-1/6b=3
Multiply the reciprocal of -1/6 to both sides, this will get x by itself
(-6/1)*-1/6b=3*(-6/1)
b= -18/1
b= -18
Answer:
285
Step-by-step explanation:
use algebra
third is x
second is 4x
first is 4x-3
x+4x+4x-3
9x-3 = x+x+1+x+2
9x-3=3x+3
12x=6, divide x=2
third is 2, sec is 8, first is 5
Answer:
4180 AED
Step-by-step explanation:
Given data
Principal= 4000
Time= 3 years
Rate= 1.5%
The compound interest expression is given as
A= P(1+r)^t
substitute
A=4000(1+0.015)^3
A= 4000(1.015)^3
A= 4000*1.045
A= 4180
Hence the worth will be 4180 AED
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.
