Answer:
y = 4
Step-by-step explanation:
Plug 3 in for 'x' in the equation and solve for 'y'...
8(3) - 3(y) = 12
24 - 3y = 12
-3y = -12
y = 4
Answer:
11x2 + 2x-13
Step-by-step explanation:
We must build the new function f-g, which turns to be a sum between polynomials.
f(x)-g(x)= 12x+20 + 11x2- 10x-33
f(x)-g(x)= 12x+20 + 11x2- 10x-33
f(x)-g(x)= 11x2 + 2x-13
The point-slope form:

- slope
- point
We have the point
and the slope 
Substitute:
