Answer:
x < 2
Step-by-step explanation:
If 2x + 3 is less than 7, then 2x alone must be less than 4.
2x + 3 < 7
2x < 4
If 2x is less than 4, then x must be less than 2.
2x < 4
x < 2
Answer:
C. Region B
Step-by-step explanation:
Since you already have the graphs of the lines, you only need to shade the proper area.
For the first equation, since y is less or equal than x-2 you have to shade the bottom part of the line.
For the second one, since y is more or equal to 1/4x+4 you have to shade the upper part of the line.
The answer is the region where the to shaded parts intersects each other.
