There are 20 miles is Sheng from his home.
Answer:

Step-by-step explanation:
Given:
From the graph shown,
The broken line means that the inequality sign will be either < or >.
The shaded region is to the left of the broken line. This means that
.
Now, in order to find equation of line, we need slope and y-intercept.
From the graph, the y intercept is at
. So, y intercept is 1.
Also, if we consider two points
on the line, then slope is given as:
Therefore, the equation of the line is given as:

But as the shaded region is to the left of the line,
∴
is the correct answer.
Answer:
Step-by-step explanation:
We are told that n = 3m + 6. Substitutte 3m + 6 for n in the second equation, obtaining:
(3m + 6) - 2m = 2, or 3m + 6 - 2m = 2.
Combining like terms yields
m = -4.
Knowing that m = -4 allows us to calculate n. Use the first equation, n = 3m + 6, for this purpose: n = 3(2) + 6 = 12.
Thus, the solution is (2, 12).
