Hey Sweetie! I'll gladly answer this question for you!
Complex numbers are "binomials" of a sort, and are added, subtracted, and multiplied in a similar way. (Division, which is further down the page, is a bit different.) First, though, you'll probably be asked to demonstrate that you understand the definition of complex numbers.
<span><span>
Solve <span>
3 – 4i = x + yi</span></span>
Finding the answer to this involves nothing more than knowing that two complex numbers can be equal only if their real and imaginary parts are equal. In other words, <span>
3 = x</span>
and <span>
–4 = y</span>
.</span>
To simplify complex-valued expressions, you combine "like" terms and apply the various other methods you learned for working with polynomials.
<span>
Simplify (2 + 3i) + (1 – 6i).</span>
(2 + 3i) + (1 – 6i) = (2 + 1) + (3i – 6i) = 3 + (–3i) = 3 – 3i
<span>
Simplify (5 – 2i) – (–4 – i).</span><span>
(5 – 2i) – (–4 – i)<span>
= (5 – 2i) – 1(–4 – i) = 5 – 2i – 1(–4) – 1(–i)= 5 – 2i + 4 + i= (5 + 4) + (–2i + i)= (9) + (–1i) = 9 – i</span></span>
You may find it helpful to insert the "1" in front of the second set of parentheses (highlighted in red above) so you can better keep track of the "minus" being multiplied through the parentheses.
<span>
Simplify<span>
(2 – i)(3 + 4i).</span></span><span>
(2 – i)(3 + 4i) = (2)(3) + (2)(4i) + (–i)(3) + (–i)(4i)<span>
= 6 + 8i – 3i – 4i2 = 6 + 5i – 4(–1)= 6 + 5i + 4 = <span>
10 + 5i</span>
<span>
That is your answer....
Hope I helped!</span></span></span>

What is the median of the set of data
Komok [63]
Problem▶293,154,254,259,267,276,263,389,253,224,215. what is the median of the set of data
Remember ▶The median will always be; an average number that is located in the center of the problem
Answer: So, therefore the median of this set would have to be: 259
0.35x=73.85, comgining moving terms
divide both sides by 0.35
x=211 quarters, which is $52.75 ANSWER
x+5=216 dimes, which is $21.60 ANSWER
That total is $74.35
<span>C = AB + D
AB = C - D
B = (C-D)/A
B = C/A - D/A</span>
I got it wrong on khan academy and this is what it said....
In conclusion, point M represents a scenario where the mixture has the intended volume and has more than the intended percent of butterfat.
