which of the following systems of inequalities has point b as a solution? explain why.

a) f(x) ≤ 3x + 4
g(x) ≤ -1/2x - 5

b) f(x) ≥ 3x + 4
g(x) ≤ -1/2x - 5

c) f(x) ≤ 3x + 4
g(x) ≥ -1/2x - 5

d) f(x) ≥ 3x + 4
g(x) ≥ -1/2x - 5

  B)  f(x) ≥ 3x + 4; g(x) ≤ -1/2x - 5

Step-by-step explanation:

Point B is above (≥) the boundary line for f(x) and below (≤) the boundary line for g(x). So, it satisfies the inequalities ...

  f(x) ≥ (3x+4)

  g(x) ≤ (-1/2x -5)
