Answer:
Step-by-step explanation:
Perpendicular lines have negative reciprocal slopes.
The exemplar equation has slope
9x - 3y = 18
- 3y = -9x + 18
y = 3x - 6
m = 3
so perpendicular slope will be -1/3
D has such a slope
3y = -x + 1
y = (-1/3)x + 1/3
Answer:

5x2=10
Answer:
6.7
Step-by-step explanation:
10% of 30000
10/100 x 30000
0.10 x 30000
=3000
In order to find how long you have to divide 20k with 3k
20000/3000 = 6.66666667
Round it up and you get 6.7
Answer:
x^2 + 2x +1 = 2x + 2
Step-by-step explanation:
(x+1) = 2
multiplying both sides by x +1
(x +1) (x+1) = 2 (x+1)
x^2 + 2x +1 = 2x + 2
