Answer:

(-5, -7)

Step-by-step explanation:

The intersection of f(x) and g(x) occurs when f(x) = g(x).

f(x) = g(x)

2x + 3 = -4x - 27

2x + 30 = -4x                          add 27 to both sides

30 = -6x                                  subtract 2x from both sides

-5 = x                                       divide both sides by -6

Thus, f(x) and g(x) intersect at x = -5. Plugging that into f(x) and g(x),

f(-5) = 2(-5) + 3 = -10 + 3 = -7

g(-5) = -4(-5) - 27 = 20 - 27 = -7

Thus, f(x) and g(x) intersect at (-5, -7).
