Rachael spins x, a number on a spinner numbered 1 through 8, and adds 15 points to it to get her score. which of the following ordered pairs show the possible scores, where x = 1, 2, 3, and 4? a. (1 , 15), (2 , 14), (3 , 13), (4 , 12) b. (1 , 16), (2 , 15), (3 , 14), (4 , 13) c. (1 , 15), (2 , 16), (3 , 17), (4 , 18) d. (1 , 16), (2 , 17), (3 , 18), (4 , 19)

D. (1 , 16), (2 , 17), (3 , 18), (4 , 19)

Step-by-step explanation:

x = 1, then y =1+15 = 16

x = 2, then y =2+15 = 17

x = 3, then y =3+15 = 18

x = 4, then y =4+15 = 19

so the ordered pairs are: (1 , 16), (2 , 17), (3 , 18), (4 , 19)

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.

ruth is 6 years old

step-by-step explanation:

6 + 24 = 30,   so 6/30 = .2  

if you do 1/5 it also equals .2, so that is the answer.
