Answer:
-1
Step-by-step explanation:
The required relation is ...
7n = n^2 -8
0 = n^2 -7n -8 . . . . put in standard form
0 = (n -8)(n +1) . . . . factor
Solutions are n=8 and n=-1.
The negative solution is -1.
Answer:
Translate from words to mathematical equation.
"n is m% of what?"
m% = m/100
what = a variable ... "x". for example.
"is" means "="
"of" means multiply
n = (m/100)•x
$1.44
each one cost 0.24
0.24 x 6 = 1.44
We simply substitute 6 into the equation:
f(6) = -2(6 - 4)² + 22
f(6) = 14
The company's profit is 14 thousand dollars
