Answer:
-1 and -5
Step-by-step explanation:
You must account for negative u values (which the abs nullifies).
So
and
is what we have to solve for.
As for usual equations, isolate the u variable.
5u + 15 = 10
5u + 15 (-15) = 10 (-15)
5u = -5

u = -1
Now you can do the same operation for the other equation and you should get u = -5.
Let's make sure we did it right by replacing u with one of our solutions (-1 or -5).

That's true. What about the other one?

Answer:
Step-by-step explanation:
d/dn(2 n^2 + 12 n + 18) = 4 (n + 3)
Indefinite integral:
integral(18 + 12 n + 2 n^2) dn = (2 n^3)/3 + 6 n^2 + 18 n + constant
Global minimum:
min{2 n^2 + 12 n + 18} = 0 at n = -3
Answer: x=2
Step-by-step explanation:
Expand
8x−24x+16=−6−5x
simplify
−16x+16=−6−5x
add 16 to both sides
16=−6−5x+16x
simplify
16=−6+11x
regroup the terms
16=11x−6
add 6 to both sides
16+6=11x
simplify
22=11x
divide
22/11=x
simplify
2=x
switch sides
x=2
