Answer:

Step-by-step explanation:

Given the equation;

$\frac{1}{z+1} +\frac{5}{z+5} = \frac{4}{z^2+6z+5}\\$ \

Find the LCM

$\frac{1(z+5)+5(z+1)}{z^2+6x+5} = \frac{4}{z^2+6z+5}\\\\1(z+5)+5(z+1) = 4\\Expand\\z+5+5z+5 = 4\\6z+10 = 4\\6z = 4 -10\\6z = -6\\z = -6/6\\z = -1\\$

Hence the value of z that satisfies the equation is -1

timofeeve [1]

Answer:

Step-by-step explanation:

The slope-intercept form of an equation of a line:

<em>m</em> - slope

<em>b</em> - y-intercept (0, b)

We have the slope <em>m = -9</em> and the y-intercept (0, -2) → <em>b = -2</em>.
