Answer:
y=9
Step-by-step explanation:
Slope: 9-9/-2-15=0
Therefore, y=0x+b
Plug values in: 9=0(-2)+b
0+b=9
b=9
Therefore, equation is y=9
Given that speed of car = x miles per hour
Time of travel = y minutes = y/60 hours
(Because there are 60 minutes in an hour)
We have to calculate distance travelled so we will use formula
Distance = speed * time
Distance = x * y/60
Distance = xy/60
Hence choice d) xy/60 is the final answer.
Answer:
x= square root of 130
Step-by-step explanation:
a^2+b^2=c^2
a=7 b=9 c=x
49+81=x^2
130=x^2
square root of 130=x
