Answer:
A. 23+x=140
Step-by-step explanation:
The angle addition postulate states that the measure of a larger angle formed by two or more smaller angles placed side by side is the the sum of the smaller angles. The angle addition postulate states that if B is in the interior of AOC , then:
 m∠AOB + m∠BOC = m∠AOC. 
From the image:
∠NOP = ∠NOQ + ∠QOP
∠NOP = 140, ∠NOQ = x, ∠QOP = 23
substituting:
140 = x + 23
x = 140 - 23 = 117
∠NOQ = 117°
 
        
             
        
        
        
Answer:
This moves f(x) 8 units to the left
Step-by-step explanation:
g(x) = f(x + 8)
y = f(x + C)	C > 0 moves it left
This moves f(x) 8 units to the left
