Answer:

Resultant is 50 mi/hr in the north east direction

Step-by-step explanation:

Plane is traveling north east at 150 mi/hr.

Now a wind is blowing from the south west at 100 mi/hr.

Now, north east and south west are directly opposite directions and such the angle between the resultant speed of the plane in flight and the wind will be;

150 - 100 = 50 mi/hr

Since the north east speed is greater than the south east speed, then the direction will be north east.

Thus, resultant is 50 mi/hr in the north east direction

Write an equation of a line that passes through the points (1, 7) and (5, 19) . Give the final form in slope intercept form. (Pl
Alinara [238K]

Answer:

y = 3x + 4

Step-by-step explanation:

slope = (y2 -y1)/(x2 - x1)

y2 = 19

y1 = 7

x2 = 5

x1 = 1

Slope = (19 - 7)/(5 - 1)

slope = 12 / 4

slope = 3

So far what you have is

y = 3x + b                      To solve for b, use either of the two points.

x = 1

y = 7

7 = 3(1) + b

7 = 3 + b

b = 4

The final equation is

y = 3x + 4                    

We should check that with the other  point

x = 5                  Find y

y = 3(5) + 4

y = 15 + 4

y = 19              Ans it checks.

Find the midpoint of the segment with the given endpoints (5,-9) and (-2,-2)
QveST [7]
Another way to solve this is to use the Midpoint Formula.  The midpoint of a segment joining points (x_1,y_1) and (x_2,y_2) is

\left(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2} \right)

So the midpoint of your segment is

\left(\frac{5+(-2)}{2},\frac{-9+(-2)}{2}\right) = \left(\frac{3}{2},-\frac{11}{2} \right)

Perhaps it helps to see that the x-coordinate of the midpoint is just the average of the x-coordinates of the points.  Ditto for the y-coordinate of the midpoint; just average the y's.

HELP ASAP WILL GIVE 15 POINTS!!!
sladkih [1.3K]

Answer:

B

Step-by-step explanation:

Since its changing the y, we now it has to be outside the x. So its not A or D. Since it moves up, its a plus. This means its not c, so it has to be B.
