Answer:
k = 9.
Step-by-step explanation:
2x + 3y -8=0
3y = -2x + 8
y = -2/3 x + 8/3
So the slope of this line is -2/3.
Therefore the slope of a line perpendicular to the above is -1 /-2/3
= 3/2.
kx - 6y = 9
6y = kx - 9
y = k/6x - 3/2
But the slope is 3/2,
So k/6 = 3/2
2k = 18
k = 9.
The sequence is changing the number -8 is multiplied by by 1 less than the previous number.
The next sequence would be -8 x -1 = 8
The answer would be D.
Answer:
-4
Step-by-step explanation:
53 = -19z+5+7z
53 = -12z+5 | -5 (on both sides)
48 = -12z | :(-12)
z = -4
