Firstly simplify your expression...by dealing with the brackets
; -k - 7k + 6n + 3n
;then substitute with the given values into your expression,
;-(-2) -7(-2) + 6(-3) + 3(-3)
; 2 + 14 - 18 - 9
; 16 - 27

Answer:

Step-by-step explanation:
We can write the equation of a line in 3 different forms including slope intercept, point-slope, and standard depending on the information we have. We have a point (8,1) and a slope from the equation y=-23x+5. We will chose point-slope since we have a point and slope.
Point slope:
in our new equation because it us perpendicular to it. This means we will need to change it into its negative reciprocal which is
.
We will substitute
and
.
.
This is the equation of the line perpendicular to y=-23x+5 that crosses through (8,1).

Answer:
z=3/11
Step-by-step explanation:
<h3>I hope it helps you</h3>
<h3>-2z+10+7z=16z+7</h3><h3>-2z+10+7z-16z-7=0</h3><h3>-11z=-3</h3><h3>z=3/11</h3>
<h3>*-2z+10+7z=16z+7 it is not a solution.This is called equation.</h3>
