Answer:
The discriminant is:
b
2
−
4
a
c
a
=
1
b
=
12
c
=
36
Substitute these values into the discriminant and you should get two answers (real roots):
12
2
−
4
(
1
)
(
36
)
=
0
If the discriminant is 0 there is 1 real root, if it is > 0 there are 2 and otherwise 0 real roots.
Step-by-step explanation:
Im pretty sure this is it, hope I could help
Total = 65
65-23=42
42/3=14
Each necklace = $14
All you need to do is subtract 4 from 10 which is 6. Then since you have four snickers bars divide six by 4. Making each snickers bar $1.50.
The error.....Kelvin just figured the 60% markdown cost...not the final price
the final price would be : 30.65 - 0.60(30.65) = 30.65 - 18.39 = 12.26
so 12.26 is the final price
or another way to do this is : if it is marked down 60%, then u r actually paying 40%......0.40(30.65) = 12.26
Answer:
It would be 2,000x+200
Step-by-step explanation:
okay it costs $200 to attend so that's a cost you are going to have to pay regardless. The $2,000 depends on how many cars you buy. So it would be 2,000 (times how ever many cars you buy) plus the $200.
