Same as any other midpoint of line segment or two points, it is the average of the two points x and y coordinates...

mp=((x1+x2)/2, (y1+y2)/2)

mp=((-6+16)/2, (-9+5)/2)

mp=(10/2, -4/2)

mp=(5, -2)

Use the midpoint formula (x1+x2)/2, (y1+y2)/2

mp= (-6+16)/2= (10)/2= 5

mp=(-9+5)/2= (-4)/2= -2

mp=(5,-2)

So, C

Answer:

– 21x^3 y – 9x^2 y^2 e) is your answer

Step-by-step explanation:

Solve the following system for A and B:

{A = 7 x^2 + 3 x y

B = -3 x y

Express the system in matrix form:

(1 | 0

0 | 1)(A

B) = (7 x^2 + 3 x y

-3 x y)

Write the system in augmented matrix form and use Gaussian elimination:

(1 | 0 | 7 x^2 + 3 x y

0 | 1 | -3 x y)

Collect results:

Answer: {A = 7 x^2 + 3 x y , B = -3 x y

then we multiply the results (7 x^2 + 3 x y) ( -3 x y) = – 21x^3 y – 9x^2 y^2

Step-by-step explanation:

it is the right answer you have to learn inverse function . if f:A to B and is a function then new function from B to A is said to be inverse function in which each element of set a maps unique element of b
