Answer:
Sally's km/h during the first half hour is 7 .
<em>The lowest average speed is between the 3rd and 4th stops.</em>
Step-by-step explanation:
On the table during the first half hour, Sally traveled 7 km.
From the first stop to the second stop, she traveled 8 km; from the second stop to the third stop, she traveled 6 km; from the third stop to the fourth stop, she traveled 3 km; from the fourth stop to the fifth stop, she traveled 4 km; and from the fifth stop to the sixth stop she traveled 8 km. Therefore The lowest average speed is between the 3rd and 4th stops.

Answer:
2y -x + 6 = 0
Step-by-step explanation:
Here a equation and a point is given to us and we are interested in finding a equation which is perpendicular to the given equation and passes through the given point .
The given equation is ,
Firstly convert this into slope intercept form , to find out the slope of the line.
Now on comparing it to slope intercept form which is y = mx + c , we have ,
And as we know that the product of slopes of two perpendicular lines is -1 . So the slope of the perpendicular line will be negative reciprocal of the slope of the given line. Therefore ,
Now we may use the point slope form of the line to find out the equation of the line using the given point . The point slope form is,
Now on substituting the respective values we have,

Answer:
see below
Step-by-step explanation:
6 - (3x+10) + 4(2 - x) =15
Distribute
6 - 3x -10 +8 -4x = 15
Combine like terms
4 -7x = 15
Subtract 4 from each side
4 -7x-4 =15-4
-7x =11
Divide each side by -7
-7x/-7 = 11/-7
x = -11/7
I think the answer is D.Hope this helps!
