When you see questions of this nature, test the individual inequalities and look out for their intersection.
For

Choose a point in the lower or upper half plane created by the line

The above line is the one which goes through the origin.
Now testing (1,0) yields,

That is,

This statement is true. So we shade the lower half of

For

We test for the origin because, it is not passing through the origin.

This yields

This statement is false so we shade the upper half.
The intersection is the region shaded in B. The top right graph
First you do 3.5z-2.7z= .8z then you divide .8 with -6, which gives you -7.5 so z= -7.5
It would be 9.54x10^6 because the nine is 6 spaces away from the decimal point if you get what i mean.
Answer:
30:80
Step-by-step explanation:
Because 300 divided by ten is 30 so 800 divided by ten is 80 :)
