The commutative property can be used because 70 • 6000 is the same as 6000 • 70.
Mark can calculate the product mentally by taking off all the zeros to get 7 • 6 which is 42. After, he can add the zeros back on. The answer is 420,000.

Answer:
Solution : Third Option
Step-by-step explanation:
The first step here is to make all the signs uniform. As you can see the third inequality has a less than sign, which we can change to a greater than sign by dividing negative one on either side, making the inequality y > - 7.

Now take a look at the third option. Of course the y - coordinate, 3, is greater than - 7, so it meets the third requirement ( y > - 7 ). At the same time 3 > 1( 2 ) > 2, and hence it meets the second requirement as well. 3 > - 3( 1 ) + 4 > - 3 + 4 > 1, meeting the first requirement. 
Therefore, the third option is a solution to the system.
