Sorry it says plus but its times
 
        
        
        
A bicyclist travels at a constant speed of 12 miles per hour for a total of 45 minutes.
We know the formula , Distance = speed * time
Speed is constant and it is 12. So it  is linear
The function becomes d = 12t, x is the t is the time and d is the distance
At the starting point, t=0  and distance d=0
End point , t=45 min = 0.75 hours and distance = 12 * 0.75 = 9
So domain (t) is { }
}
Range (d) is { }
}

Hey there!!
Okay here are the steps you can follow!
9 11/12  ---->  improper fraction  ----> 119/12
2 8/11  ---->  improper fraction  ---->  30/11
119/12  -  30/11
(119/12  -  30/11) * 132
11(119)  -  12(30)
1309 - 360
<u>949</u>
        
             
        
        
        
Jk= 18
Kl= 10
3x - 2 = 28
+2. +2
3x / 3 and 30 / 3 = 10 
28-10 = 18
