Help me with this please :)
shtirl [24]

Answer:

second option

G(3 , -4) ; H(8 , 1)

Step-by-step explanation:

For the line GH  to be a median, the point G must have the intermediate value at x and at y between points A and B, and the point H must have the intermediate value at x and at y between points A and B

G = (Ax + Bx)/2 , (Ay + By)/2

G = (3 + 3)/2 , (-9 + 1)/2

G = 6/2 , -8/2

G = (3 , -4)

H = (Cx + Bx)/2 , (Cy + By)/2

H = (13 + 3)/2 , (1 + 1)/2

H = 16/2 , 2/2

H = (8 , 1)

This is because for a medium to be the point p has to be right in the middle of the other 2 vertices

What are two numbers that multiply to equal -24 but add to equal +2
Sav [38]

Answer:

  6 and -4

Step-by-step explanation:

The sum is near 0, so the factors will be near √24, approximately 5. From your knowledge of multiplication facts, you know that 4×6 = 24.

The product will be negative when one of these factors is negative. Since you want a positive sum, the larger one must be positive.

  The numbers are 6 and -4.
