Algebra 2 need help on a ( ABC )

Answer:
b)
[tex]x = \frac{15}{4} [/tex]
Step-by-step explanation:
b) set up equations so they are equal to each other,
[tex]2x - 2 = - 3x + 12[/tex]
[tex]5x = 14[/tex]
[tex]x = \frac{14}{5} [/tex]
this is when f(x)=g(x) so our approximation was close.
c)solving it graphically is nearly impossible because the solution can be any value around the intersection. only way to be sure is to solve it symbolically.
