Which algebraic rule describes the transformation? a) (x, y) → (x + 1, y − 3) b) (x, y) → (x + 3, y − 1) c) (x, y) → (x − 1, y + 3) d) (x, y) → (x − 3, y + 1)

It's B.

Step-by-step explanation:

(x, y) ---> (x + 3, y - 1)

Using point X as an example:

(x, y) ---> (x + 3, y - 1)

(0, 0) ---> (0 + 3, 0 -1)

(0, 0) ---> (3, -1)

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3

17

step-by-step explanation:

51/3=17

thus 17 is your answer.
