12(9y + 10b + 11), for y = 3 and b = 5

12(9y + 10b + 11)

substitute y=3 and b=5

12 ( 9*3 + 10*5 +11)

12(27+50+11)

12(88)

1056

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
