53=20+x
Subtract 20 from 20 and 53
33=x
Hope this helps!
P.S.
Nice tab theme :P
Answer:
(y - 4) = 2 (x -3)
=> y - 4 = 2x -6 => y = 2x -6 + 4 = 2x - 2
If 4 is a root, then a factor must be x - 4.
Only choices A and D have x - 4 as a factor.
Now look at the constant term of each binomial in the factorizations of choices A and D.
A.: -4, 4, 5
Their product is -80.
The constant term of the original polynomial is -40, so this factorization cannot be correct.
D.: -4, 2, 5
Their product is -40.
This is the correct factorization.
Answer: D.
