Answer:

The midpoint is (-1,-7)

Step-by-step explanation:

To find the x coordinate of the midpoint, add the x coordinates together and divide by 2

(-3+1)/2 = -2/2 =-1

To find the y coordinate of the midpoint, add the y coordinates together and divide by 2

(-5+-9)/2 = -14/2 =-7

The midpoint is (-1,-7)

If a plane can travel 490 miles per hour with the wind and 390 miles per hour against the​ wind, find the speed of the wind and
abruzzese [7]
Let the speed of plane in still air be x and that wind be y
therefore:
x+y=490
x-y=390
next we solve for the values of x and y, first we add the above equations. This will give us:
2x=880
x=880/2
x=440 miles per hour.
substituting the value of x in one of the equations and solving for y we get:
440+y=490
y=490-440
y=50 miles per hour
