Answer:
C
Step-by-step explanation:
To find (g ○ f)(x), substitute x = f(x) into g(x) , that is
g(2x - 5)
= 3(2x - 5) + 4
= 6x - 15 + 4
= 6x - 11 → C
2 because you can evenly split it in half 2 different ways
Answer:

Step-by-step explanation:
So we have the equation:

Subtract 4 from both sides:

Divide both sides by -12:

Simplify and reduce:

2x+y-10=0
2x+y=10 ------------------->(1)
x-y-5=0
x-y=5------------------------>(2)
(1)+(2); 3x=15
x= 5
(x=5) substitute in (1); y=0
