Plz asap! i will give 35 points for next question !

k is the shift up and down

so  to shift it down K < 0

h is the shift left and right

a positive shifts left

h>0

Choice C

i'm assuming it's looking for the missing length, which should be 4cm

hope this !

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
