The minimum happens at x = -b/2a
x = -30 / 2(3) = -30/6 = -5
Now replace x in the equation with -5 and solve:
3(-5)^2 + 30(-5) +27 = 75 - 150 + 27 = -48
The minimum is at (-5,-48)

Answer:
x = 7
Step-by-step explanation:
Since BD is the angle bisector of ∠ABC, then
∠ABD = ∠CBD, that is
2x + y = 14 + y ( subtract y from both sides )
2x = 14 ( divide both sides by 2 )
x = 7

Answer:
$677.18
Step-by-step explanation:
Data provided in the question:
Bill’s nominal income in 1990 = $1,009 per month
CPI value in the year 1990 = 149
CPI value in the year 2017 = 192
Now,
The Consumer price index ( CPI ) is given as :
CPI = 
thus,
for the given case of year 1990
149 = 
or
Real income in 1990 = 
or
Real income in 1990 = $677.18
