Answer:
5ax + 5ay = 5a(x+y)
Step-by-step explanation:
Answer:
c
Step-by-step explanation:
If the dot product of the vectors is zero then they are perpendicular
(5, - 1) • (- 3, 6)
= (5 × - 3) + (- 1 × 6) = - 15 + (- 6) = - 15 - 6 = - 21 ≠ 0
Since product is not zero vectors are not perpendicular
Answer:
.6
Step-by-step explanation:
Try plugging in 4,6, and -7 into the x's
