3-2i/1+4i include each step necessary in simplifying
Likurg_2 [28]

Answer:

\frac{3-2i}{1+4i}=\frac{11}{17}-\frac{10}{17}i

Step-by-step explanation:

\frac{3-2i}{1+4i} <-- Given

\frac{3-2i}{1+4i}*\frac{1-4i}{1-4i} <-- Multiply by the conjugate of the denominator as a factor of 1

\frac{(3-2i)(1-4i)}{(1+4i)(1-4i)}

\frac{(3)(1)+3(-4i)-2i(1)-2i(4i)}{(1)(1)+1(-4i)+4i(1)+4i(-4i)} <-- Use the Distributive Property and FOIL

\frac{3-12i-2i-8i^2}{1-4i+4i-16i^2}

\frac{3-10i-8i^2}{1-16i^2}

\frac{3-10i-8(-1)}{1-16(-1)} <-- Rewrite i^2 as -1

\frac{3-10i+8}{1+16}

\frac{11-10i}{17}

\frac{11}{17}-\frac{10}{17}i <-- Rewrite in a\pm bi form

Arlecino [84]

Answer:

x = \frac{9}{2}

Step-by-step explanation:

x - 2 (x - \frac{3x}{2}) = 2 (4 - x) + 10

x − 2 × \frac{-x}{2} =2(4−x)+10

x−(−x)=2(4−x)+10

x+x=2(4−x)+10

2x=2(4−x)+10

2x=8−2x+10

2x=−2x+18

2x+2x=18

4x=18

x = \frac{18}{4}

x = \frac{9}{2}

What is the solution of this system of equations: 5x=-10-5y; 5x+10y=-25
nikitadnepr [17]
5x=-10-5y
Add 5y for both side
5x+5y=-10
-
5x+10y=-25
=
-5y=15
Divided -5 for both side
y=-3
5x+10y=-25
5x+10(-3)=-25
5x-30=-25
Add 30 for both side
5x=5
Divided 5 for both side
x=1. Hope it help!
