Easy, just divide
kelly=440mi/8hr=220mi/4hr=110mi/2hr=55mi/1hr
alberto=468mi/9hr=156mi/3hr=52mi/1hr
55>52
kelly drove 55mi in 1 hour
55-52=3
she drove 3 miles more in 1 hour
Step-by-step explanation:
angle AOB = x+3
angle AOC = 2x + 11
angle BOC = 4x-7
angle AOC = angle AOB + angle BOC
=> 2x +11 = (x+3) + (4x-7)
2x +11 = 5x - 4
=> 3x = 15
x = 5
subst x = 5 in the given formulas
angle AOB = x +3 =8
angle AOC = 2x + 11 = 21
angle BOC = 4x - 7 = 13
The constant is 3 because it has no variable.
The coefficient is 7b because it has a variable.
Yo sup??
By observing the graph we can say that minimum value of Toretto graph occurs at x=-3
whereas the minimum value of OConner graph occurs at x=3 .
In the given figure the minimum value is at x=3
therefore OConner is correct because the vertex is (3,1)
Hope this helps
