Answer:
The answer to your question is: k(-5) = -115
Step-by-step explanation:
Function k(n) = n³ - 3n find k(-5)
k(-5) = (-5)³ - 3(-5) substitution
k(-5) = -125 + 15 simplify
k(-5) = -115
30b+3= s
It would be thirty students times the number of buses, with an addition of 3 students equal to the total number of students when on the field trip.

Answer:
x = 0
Step-by-step explanation:
Since the product is not equal zero, we need to multiply both parenthesis first:
Add 27 from both sides:
Factor 
out:
Apply the zero product:
The solutions of the equation are 
and 
.
We can conclude that the correct answer is x = 0.
Answer:
x = 14
y = 30
Step-by-step explanation:
x + 10 = 3x - 18
x = 3x - 18 - 10
x = 3x -28
x - 3x = -28
-2x = -28
x = 14
(3x - 18) + (6y - x - 10) = 180
3x - x -18 - 10 + 6y = 180
2x - 28 + 6y = 180
2x + 6y = 180 + 28
2(14) + 6y = 208
6y = 208 - 28
6y = 180
y = 30

Answer:
2
Step-by-step explanation:
This equation will use substitution, in this equation we'll substitute the given value, 14 for p.
<u />
<u>Substitute 14 in for p:</u>
14/2 - 5
<u>Let's solve:</u>
14/2 - 5
=7 - 5
=2.
