Answer: 17 
Step by step : 146+2x=180 
 2x=34
 X=17
        
             
        
        
        
Answer:
x = -2 3/5
Step-by-step explanation:
 
        
             
        
        
        
4x + 9 = 68
Subtract 9 from both sides:
4x = 59
Divide both sides by 4
X = 59/4
X = 14.75
 
        
                    
             
        
        
        
Answer: 
By taking (-1, 1) and translating it left by 2 and up by D we have (-3, 1+D)
Rotating 90° counterclockwise puts a negative on your y-coordinate and switches the x and y-coordinates.
Final answer:
(-1-D, -3)

A open circle means that x is < or >.
A closed circle means that x is ≤ and ≥.
--------------------------------------------------
Answer: A) x > -8 or x ≥ 5
--------------------------------------------------
Explanation: Their are two dots on the number line. One being a closed dot and the other being an open dot. The open dot symbolizes that x needs to be greater than -8. The closed dot symbolizes that x needs to be less than or equal to 5.
