Lines K and N are perpendicular If the slope of line K is -6, what is the slope of Line N
djverab [1.8K]

line N has slope m = \frac{1}{6}

given a line with slope m then the slope of a line perpendicular to it is

m_{perpendicular} = - \frac{1}{m}


thus line N has slope - \frac{1}{- 6} = \frac{1}{6}

Answer:AGC and DGH are opposite angles.

Step-by-step explanation:

So, Y+10=3x-40

Y-3x40=-50

y-120=-50

y=-50+120

y=70

What is the square root of -6.76
mojhsa [17]

Answer:

2.6i

Step-by-step explanation:

undo the - by making it:  √-6.76= √6.76 x  √-1

then,  √-1 would be converted to imaginary number -> i

now rewrite it as  √6.76 x i or i√6.76 which is the same as the squareroot of 6.76 which is 2.6 times i.

Then just write your final answer as 2.6i
