Part A: The shading is in between the lines. The line for y<4x-2 is dotted, while the line for y<span>≥(-5/2)x-2 is solid</span>. The solution area is below the line y=4x-2 and above the line y=(-5/2)x-2.
Part B: (-2,-2) is not in the solution area. We can plug (-2,-2) into the inequalities: -2<4(-2)-2, and -2<(-5/2)(-2)-2. However neither of these are true so it is not a solution.
Answer:
x

Explanation:
simply subtract each term in the second equation from the first equation:
3
x
+
4
y
=
−
8
3
x
+
16
y
=
−
32

You are 42 years old. (21 x 2 = 42)
Your son’s age is 9 years old (42 - 24 = 18, 18 / 2 = 9)
Answer:
