Determine the missing number for this sequence.

24.5

Step-by-step explanation:

To help find the missing number subtract 19 and 13.5=5.5

Then subtract 5.5 from 30,

30-5.5=24.5

You can test this by subtracting 5.5 from every known number and you should get

30-5.5=24.5,

24.5-5.5=19,

19-5.5=13.5, and so on.

step-by-step explanation:

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
