Answer:
Option D.
Step-by-step explanation:
Consider option D. 
Take point (0,0)
On putting this point in inequation 
, we get
which is true . So, solution is region towards the origin i,e region below the line 
including the line itself .
On putting (0,0) in inequation 
, we get 
which is false , so solution is region away from the origin i.e region below line 
including the line itself .
So, common solution to both the inequations is the shaded part in the given figure .
In other words, we can say that the graph shown in the given figure represents system of equations:
<u>Answer: </u>
Option (c)
The average speed between 2.8 km and 4.2 km is 42 km/h
<u>Explanation:</u>
Given, the distance between 2.8 km and 4.2 km is 4.2 - 2.8 = 1.4 km
Time (in hours) between 2.8 km and 4.2 km
= 0.084 – 0.051
= 0.033 hr
Speed =
Speed = 
Speed = 42.4 km/hr = 42 km/h (rounded to nearest)
Therefore, the average speed between 2.8 km and 4.2 km is 42 km/hr
Hence, Option (C) is correct
60,000+3,000+20+9 in standard form is 6.3029 x 10^4.
Hope this helps you!
