Answer:
y=3/5x+1 because when a line is perpendicular to another line the slope it the opposite meaning negative to positive or positive to negative
you also reverse the number/ fraction...for example, if the slope was 2 the slope in the other equation would be -1/2. if the slope in the first equation was 1/2 the second equation slope would be -2 since it is the opposite and flipped
Step-by-step explanation:
A.
I=prt
I=(3800)(.055)(4/12)
I=$69.67
b.
Principal-interest=money received from Bank
3800-69.67=$3730.34
c.
I=prt
69.67=3730.34(r)(4/12)
69.67=1243.45r
69.67/1243.45=1243.45/1243.45r
.056≈r

3.5 books in 1.75 weeks
X books in 1 week
3.5/1.75=2 books
If 5 in 25 people make a preorder, the remaining people in that study group did not. By subracting the people who pre-ordered from the total people the people without preorders will be found
People without preorders = 25-5 =20
20 people didn't preorder
Well if each set had 12 cards. So 18*12 = 216 :D
