Perpendicular is when the slopes multiply to negative 1
remember
the slope of the line in form
ax+by=c is -a/b
find slopes
2x+ky=6
slope is -2/k
6x-4y=12
slope is -6/-4=3/2
so
-2/k times 3/2=-1
solve for k
-6/(2k)=-1
times both sides by 2k
-6=-2k
divide by -1
3=k
k has to be 3

Answer:
Absolute deviation is when you find the mean of a data set, then the difference between each number and the mean, then the average f the differences.
Step-by-step explanation:
Maddox: |10-9| = 1
Enrique: |10-13| = 3
Gloria: |10-9| = 1
McKenna: |10-10| = 0
Asher: |10-9| = 1
Hannah: |10-9| =
Danielle: |10-10| = 0
Katy: |10-10| = 0
Timothy: |10-11| = 1
Gentry: |10-9| = 1
Now you have the numbers: 1, 3, 1, 0, 1, 1, 0, 0, 1, 1,
Now find the mean of those numbers:

The absolute deviation is 1.
Answer:
a. -2
Step-by-step explanation:
2x^2 + 9x + 4 = 0
x^2 + 9/2*x + 2 = 0
x = - 9/4 +- √(81/16 - 32/16) = - 9/4 +- 7/4
x1 = - 1/2
x2 = - 4
