Answer: 0; Yes
Step-by-step explanation:
-8 x 4.5 = -36
2 x 18 = 36
-36 + 36 = 0
since the product is zero, the vectors are perpendicular
The answer is B if they are fractions.

Have a good day.
Answer:
C
Step-by-step explanation:
Calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = (4, 9) and (x₂, y₂ ) = (12, 20)
m = 
= 
→ C
92 males buy tickets so
200-92=108
so 108 females buy tickets
30 males buy business and a total of 44 people (female and male) but business so 44-30=14
14 females buy business
108-14(business ticket) = 94 females left.
62 of those 94 females buy economy tickets
so therefore 94-62=32. 32 females left over
14 females = business
62 females = economy
14 + 62 = 76
108 - 76 = 32
32 remaining females buy premium
it says a total of 60 people buy premium so 60 - 32 = 28
so 28 males buy premium
hope this helped
