Answer:
The residual of the point in the equation
is
Step-by-step explanation:
We have been given point where
.
Now the equation is .
Plugging the value of in the equation of
,
we have to find the predicted value of y and .
So y predicted .
To find the residual point we have to subtract the actual value from the predicted value.
As actual value of along with the points
.
Residual point = Actual value - Predicted value.
So the residual for the point is
.
Let, speed of 1st bicyclist is x.
So, speed of 2nd bicyclist is x-3 .
We know, relative speed when two objects moves towards each other :
Now, distance travelled in 3 hours is (98-2) miles .
So,
Therefore, speed of bikes are 17.5 mph and 14.5 mph.
Hence, this is the required solution.
