Answer:
<em>angle KNM = 131 degree</em>
Step-by-step explanation:
angle MNJ = angle KNL ( vertically opposite angles)
angle KNM + angle KNL = 180 degree ( linear pair)
8x-5 + 4x-19 = 180 degree
8x + 4x -5 -19 = 180
12x - 24 = 180
12x = 180+24
12x= 204
x= 204/12
x= 17
angle KNM = 8x-5
= 8(17) -5
= 136 -5
= 131
Angle KNM = 131 degree

Answer:
slope is -1/2 and y- intercept is 1/3
Step-by-step explanation:
use y=mx+b
m=slope
b= y-intercept
rearrange your equation
y=1/3-1/2x
y=-1/2x+1/3
Answer:
Solution set= {(3,-9)}
Step-by-step explanation:
x² +6x-27=0
x² +9x-3x-27=0
x(x+9) -3(x+9)=0
(x-3)(x+9)=0
x-3=0; x+9=0
x=3; x=-9
