The coordinates of point t are (0,2). the midpoint of st is (1,-6) find the coordinates of point s.

Question

the coordinates of point t are (0,2). the midpoint of st is (1,-6) find the coordinates of point s.

(10,-14)

Step-by-step explanation:

0 + x

  = 5            Multiply both sides by 2 >   0 + x = 10  or x = 10

   2

2 + y

  = -8         Multiply both sides by 2  >  2 + y = -16   or y = -14        

   2

Therefore, the coordinates of point S should be at (10,-14)

the answer is b.)

< 1=< 2

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
