(f+g)(x)=0
f (x) + g (x)=0
now,
substitute their values
x^2 -4x + x -18 = 0
x^2 -3x -18 =0
x^2 - 6x + 3x - 18 =0
x (x-6) + 3 (x-6) = 0
(x-6)(x+3) = 0
we have to find it's zeroes (or roots) now:
x-6 =0
x = 6
x +3 =0
x = -3
Answer:
Step-by-step explanation:
The answer is acd
For the one it
X>6
For the second one it’s x ≤ −1

From the code key, we can see that each number represent the alphabet at that position;
To do this, we simply replace each number with the alphabet they represent.
So, we have:
16-11-13-5-10 => P-K-M-E-J
2-15-18 => B-O-R
13-23 = > M-W
8-11-17 => H-K-Q
11-12 => K-L
22-11-12-19 => V-K-L-S
