Answer:
First option: 
Step-by-step explanation:
The missing graph is attached.
The equation of the line in Slope-Intercept form is:

Where "m" is the slope and "b" is the y-intercept.
We can observe that:
1. Both lines have the same y-intercept:

2. The lines are solid, then the symbol of the inequality must be
or
.
3. Since both shaded regions are below the solid lines, the symbol is:

Based on this and looking at the options given, we can conclude that the graph represents the following system of inequalities:

Answer:
14
Step-by-step explanation:
Plug the 5 into the equation
2(5) + 4 = 14
1. x=6
2. y=6
3. x=10
4. y=10
1.c+9= 19
2. 9-y=7
3. 5y=30
4. u-u=0
1. 2(3x2 - 5x3)
2(6-15)
2x(-9)=18
