Answer:

Z = 258Ω

Step-by-step explanation:

There are two methods of solving this question,

First method

Z = ( RXL)/ sqr rt ( R²+XL²)

Z= (330 Ω × 420 Ω)/ sqr rt ( 330 Ω² + 420 Ω²)

Z = 138600 Ω /534

Z = 259 Ω

THE second complete method is given in attachment below

–x – 7 = 16 please help me

Move the -7 to the right, its sign will flip (do you know why?)
Negate both sides to change -x to x

-x = 16+7
-x = 23
x = -23

<h3>What is the equation of a line passing through two given points in 2 dimensional plane?</h3>

Suppose the given points are (x_1, y_1) and (x_2, y_2), then the equation of the straight line joining both two points is given by

$(y - y_1) = \dfrac{y_2 - y_1}{x_2 - x_1} (x -x_1)$

The equation of the line is found as;

$\rm y-y_1= \frac{y_2-y_1}{x_2-x_1} \\\\ \rm y-9= \frac{31-9}{2+5} (x+5)\\\\ 7y-63 = \frac{31-9}{2+5} (c+5)\\\\ 7y-63=22x+110\\\\ 7y= 22x+173 \\\\ but ,x=13\\\\ 7y=22 \times 13 +173\\\\ y= \frac{1259}{7} \\\\ y= 179$
