Answer:
Step-by-step explanation:
The graph will open upwards
Shifted to the right by 5
Vertex: (5,0)
Domain: x= All Real Numbers
Range: y
0
Set up the equation ... 60 + 40X = total charges... where X is the number of hours (8.5)
60 + 40(8.5) = ?
60 + 340 = ?
400 = total charges
Let's find the least possibilities:
First number: 6
Second number: 8
Third number: 10
6 + 8 + 10 = 24
Now we can see that we are still missing 31 - 24 = 7.
7 can be gained by adding 3 and 4, so:
First number: 6 + 3 = 9
Second number: 8 + 4 = 12
Third number: 10
9 + 12 + 10 = 31
11/2x=2
2/11(11/2)x=2(2/11)
x=4/11
Answer:
its 11 or its 5
