Answer:
11
Step-by-step explanation:
Those are alternate exterior angles.  IF the lines A and B are parallel, then those angles are equal.  Set them equal to each other and solve for x:
5x + 9 = 6x - 2
Combine like terms:
11 = x
 
        
             
        
        
        
To get slope use
y2 - y1 / x2 - x1
10 - 8 / 1 - 0 = 2/1 = 2
Slope = 2
The y-intercept is the coordinate point that has 0 as the x value.
(0, 8) is the y-intercept.
        
             
        
        
        
For this case what you must do is find the diagonal of the square to find the diameter of the circle and then be able to obtain the radius.
 We have then:
 A = L ^ 2 = 128
 L = root (128)
 L = 11.3137085
 Then, the diagonal of the square knowing its sides is:
 d = root ((L) ^ 2 + (L) ^ 2)
 d = root ((11.3137085) ^ 2 + (11.3137085) ^ 2)
 d = 16 feet
 Finally the radius of the circle is:
 r = d / 2
 r = (16) / 2
 r = 8feet
 answer:
 the radius of the circle is
 r = 8feet
        
             
        
        
        
Alright so basically what you have to do here is realize that 130 miles is 2 hours, so if you divide by 2, you’ll have 65 miles in one hour ,, so 6mph, and if you divide again by two, you have 32.5 miles ,, therefore he travels 32.5 miles in 30 minutes
        
             
        
        
        
Answer:
8
Step-by-step explanation:
The perimeter is the sum of the 3 sides of the triangle.
let the other 2 sides be x and x - 3 , then
12 + x + x - 3 = 31
2x + 9 = 31 ( subtract 9 from both sides )
2x = 22 ( divide both sides by 2 )
x = 11 and x - 3 = 11 - 3 = 8
The 3 sides are 12, 11, 8
with shortest side 8
