Let a=⟨−1,−2,3⟩a=⟨−1,−2,3⟩ and b=⟨−5,4,−4⟩b=⟨−5,4,−4⟩. Show that there are scalars ss and tt so that sa+tb=⟨−18,20,−22⟩sa+tb=⟨−18,20,−22 ⟩ You might want to sketch the vectors to get some intuition.

answer: 15

step-by-step explanation:

only 10/60 isn't equivalent

hope this : )

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
