Answer is a, 57.49.
17.42-12.60-9.62= $-4.80+62.29=57.49
Answer:
Slope EQUALS: 
Step-by-step explanation:
y=-x+3
Use quadratic formula
if you had ax^2+bx+c=0, then
x=

a=1
b=?
c=34
subsitute

=5+/-3i

=5+/-3i
make 5+/-3 into fraction over 2,(10+/-6i)/2

=(10+/-6i)/2
multiply both sides by 2

=10+/-6i
we conclude that -b=10
b=-10
ok so equaton is
x^2-10x+34
11/2 + 3/4 = 22/4 + 3/4 = 25/4
(25/4) / (1/8) = 25/4 * 8/1 = 200/4 = 50 students
You would multiply 7,962 by 10 which would give you 79,620 if I am correct
