Answer: B
Step by Step
5y + 6 = -3X
5y = -3X - 6
Y = -3/5X -6/5
Perpedicular is the flip of your slope so -3/5 becomes 5/3X
Answer:
1/5
Step-by-step explanation:
1/9=0.11
1/3=0.33
1/5=0.20

Because it does not specify that she has to choose one or two from each category all pieces of jewelry can be treated as choices in a combination set.
the formula for a combination is

where n is a total number of choices ( 11 )
and r is number chosen out of those choices (4)
so
C(11,4)= \frac{11!}{4!(11-4)!}
She has 330 possible choices to come home with 4 pieces of jewelry
