Find the values of x and y that satisfy the equation.<br><br> 4x+2i=8+yi<br> x= <br> and y=

stiks02 [169]

Answer:

The values of x and y that satisfy the equation are 2 and 2, respectively.

Step-by-step explanation:

Two complex numbers are identical if and only each pair of respective coefficients are identical on both sides. Then, we need to observe the following conditions:

Real component

$4\cdot x = 8$ (1)

Imaginary component

$2 = y$ (2)

The solution of this system of equations is $x = 2$ and $y = 2$ .

The values of x and y that satisfy the equation are 2 and 2, respectively.

X - the number

$2(2x+7)=-8x+2 \\
4x+14=-8x+2 \\
4x+8x=2-14 \\
12x=-12 \\
x=\frac{-12}{12} \\
x=-1$

The number is -1.

There are no results for The impedance Z in an AC (alternating current) circuit is a measure of how much the circuit impedes (hi

Semmy [17]

Answer:

Step-by-step explanation:

If the impedance is related to the voltage and the current by the formula V = IZ where;

V is the voltage

I is the current

Z is the impedance

Given

I = 0.4+3i

V = 0.3-2i

Voltage V = (0.4+3i)(0.3-2i)

V = 0.4(0.3)-0.8i+0.9i-6i²

V = 0.12+0.1i -6i²

Since i² = -1

V = 0.12+0.1i-6(-1)

V = 0.12+0.1i+6

V = 6.12+0.1i.

Hence the impedance is 6.12+0.1i
