Answer:
Step-by-step explanation:
It will only take into account private cost because it is allowed to emit pollution at a zero cost.
Because the reciprical is the opposite, it is true. I hope this helps!
For this case we must factor the following quadratic expression:
To factor, we must find two numbers that when multiplied give as result +9 and when added or subtracted give as result -6.
These numbers are:
-3 and -3
So, we have:
ANswer:
Option D
For 2 1/2 = (5/2) Yards, her cost was = 15
So, for 1 yard, it would be: 15 / 5/2 = 15*2/5 = 30/5 = 6
In short, Your Answer would be $6
Hope this helps!
Y=3x²-6x+4
to put in vertex form, make a square by adding (half of b)²
but first, we have to make a=1 by take out the 3:
y=3(x²-2x)+4
b=-2, half of b=-1, (-1)²=1, so add 1, then subtract 1 inside the parenthesis:
y=3(x²-2x+1-1)+4
make the square: y=3[(x-1)²-1]+4
simplify: y=3(x-1)²-3+4=3(x-1)²+1
so the answer is A.
