Answer:
The first option: -5/4x + 1/6. 
Step-by-step explanation:
(3/4x - 2/3) - (-5/6 + 2x)
= (3/4x - 2/3) + 5/6 - 2x
= 3/4x - 2x - 2/3 + 5/6
= 3/4x - 8/4x - 4/6 + 5/6
= -5/4x + 1/6
So, the first option: -5/4x + 1/6. 
Hope this helps!
 
        
             
        
        
        
Answer:
 y-intercept is the value of y when x is equal to zero. Because the y intercept is a point on a graph, you'll usually write it in point/ coordinate form.
Step-by-step explanation:
The y-intercept is where the parabola of a function crosses (or intercepts) the y axis.
 
        
             
        
        
        
The sum of two sides of a triangle must be greater than the third side
1) 5+9>14
14>14 It is incorrect so you can’t have these lengths 
2)7+7>15
14>15 X 
3)1+2>4
3>4 X
4)3+6>8 
9>8
6+8>3
14>3
8+3>6
11>6
So the fourth choice is correct 
        
             
        
        
        
If two angles are supplementary, their sum equals 180 degrees
        
             
        
        
        
You paid $4.76 total for 7 notebooks. To figure out how much each individual notebook cost, you divide the total cost by the number of things you bought, so
Cost of One Notebook = Total Cost of Notebooks / Number of Notebooks = $4.76 / 7 = $0.68
This is the unit rate.
To buy three notebooks, you just calculate the total cost of three notebooks at this price point, so
Cost of Three Notebooks = Cost of One Notebook * 3 Notebo0ks = $0.68 * 3 = $2.04
