These two graphs have the same slope (3), and are therefore parallel. Parallel lines never intersect each other.
Answer
48 Days
Explanation
3(days) times 16= 48 days
6x + 18y = 18. Let us take x = 0
6(0) + 18y = 18
0 + 18y = 18
18y = 18
y = 18/18
y = 1
(0, 1) [x = 0, y = 1]
6x + 18y = 18. Let us take y = 0
6x + 18(0) = 18
6x + 0 = 18
6x = 18
x = 18/6
x = 3
(3, 0) [x = 3, y =0]
Infinite solutions can be found for x and y
Answer:
D = - 9
Step-by-step explanation:
D - 7 = -18
D - 7 + 7 = -18 + 7
D = -9
