Answer:
the third one
Step-by-step explanation:
bc like there are 2 boxes of 1 and 5 boxes of 1/6 so thats already 2 and 5/6 which applies to all of them. then there is 1 box of 1 and 2 boxes of 1/3 so thats 1 and 1/3 which applies to all of them also but when you make them have the same denominator you get 2 and 5/6 + 1 and 4/6 which deletes the second one. When you add you should get the same denominator so that deletes the first one so then you simplify that and the fraction should still be equal to the unsimplified fraction so you should get 4 and 1/2 if that makes sense
Answer:
Step-by-step explanation:
(-8,1) is ⊥ to y=2x-17
from y=mx+c
comparing with
y=2x-17
m₁₌2
for perpendicularity m₂=-1/m₁
m₂₌-1/2
equation of a line with one point y-y₁/x-x₁=m
(-8,1) are x₁ and y₁ respectively
y-1/x-(-8)=-1/2
y-1/x+8=-1/2
cross multiply
2(y-1)=-1(x+8)
2y-2=-x-8
2y=-x-8+2
2y=-x-6
divide both side by 2
y=-1/2x-3
