Answer:
1st . The shaded region of the graph ....
2nd. The graph line is solid.
4th. The ordered pair (2 ; 5) is part of the solution set.
Step-by-step explanation:
. Because y is <u>greater</u> or equal than the line, everything above the line is part of the solution.
. Since y is greater or<u> equal</u>, the line is solid. If y was only greater the line would have been dotted.
. The pair (2 ; 5) represent the x = 2 w/ y = 5, and reading the graph you can see the at this point the lines passes through it.
3.) 3 faces. 4 edges. 3 V
4.) 5 faces. 5 edges. 3 V
5.) 2 faces. 1 edge. 1 V
6.) 3 faces. 0 edges. 1 V
7.) 1 face. 0 edges. 2 V's
I'm iffy on the V's.
Answer:
Step-by-step explanation:

Answer:
y=20
Step-by-step explanation:
0.6(y-10)=6
0.6y-6=6
0.6y=6+6
0.6y=12
y=12/0.6
y=20
the mistake is added 10 to both sides
