2)
4x-10y=12
Subtract 4x from each side.
-10y=-4x+12
Divide both sides by -10
y=2/5x-6/5
3)
13=1/6y+2x
Subtract 2x from each side.
-2x+13=1/6y
Multiply both sides by 6.
-12x+78=y
Flip it around.
y=-12x+78
Hope this helps!
        
             
        
        
        
Answer:
h = 55
Step-by-step explanation:
the sum of the 3 angles in a triangle = 180°
the 2 unknown interior angles = 180 - 2h ( straight angle ), hence
the sum of the 3 angles
180- 2h + 180 - 2h + 40 = 180
400 - 4h = 180 ( subtract 400 from both sides )
- 4h = - 220 ( divide both sides by - 4 )
h = 55
 
        
             
        
        
        
Answer: I think it’s neither 
Explanation:
The line is parallel unless the slope is the same and with a different y-intercept
The line are perpendicular unless the one of the slope is the negative reciprocal of the other. 
And both equation didn’t meet any of the requirement.
        
             
        
        
        
Answer:
13 miles
Step-by-step explanation:
3 1/4 can be changed to 3.25
Then multiply 3.25 (the time) and 4 (the distance per hour) to get 13.
