You start at (1,9) you move left 1 unit and up 1 unit. where do you end?

(0, 10)

Step-by-step explanation:

x=1 y=9

Up 1 means add 1 to the y coordinate

Left 1 means subtract 1 from the x coordinate

(1-1, 9+1)

(0, 10)

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i

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
