In the graph, for x on the interval [-7,6), the function y=0
[ ] represents the greatest integer than x without going over
In the interval [-7,6) the value of the greatest integer function is -7
To get y=0 we must add 7
Then the graph is y=[x]+7
Answer: Option A. y=[x]+7
57
95% is 19/20 as a fraction. 60/20 is 3. Multiply 19 by 3 to get 57. At least that how I do it. Hopefully this helped you.

Answer:
85 km/h
Step-by-step explanation:
Let s represent the speed of the slower car. Then the travel time is ...
time = distance/speed
2 = 360/(s +(s+10))
4s +20 = 360 . . . . . multiply by 2s+10
4s = 340 . . . . . . . . . subtract 20
s = 85 . . . . . . . . . . . divide by 4
__
The rate of the slower car is 85 km/h.
