Find all the critical values
Natalija [7]
              y - 3
g(y) = ------------------
            y^2 - 3y + 9

To find the c. v., we must differentiate this function g(y) and set the derivative equal to zero:
     
             (y^2 - 3y + 9)(1) - (y - 3)(2y - 3)
g '(y) = --------------------------------------------
                    (y^2 - 3y + 9)^2

Note carefully:  The denom. has no real roots, so division by zero is not going to be an issue here.  

Simplifying the denominator of the derivative, 

(y^2 - 3y + 9)(1) - (y - 3)(2y - 3)  =>  y^2 - 3y + 9 - [2y^2 - 3y - 6y + 9], or
                                                         -y^2 + 6y

Setting this result = to 0 produces the equation y(-y + 6) = 0, so
y = 0 and y = 6.  These are your critical values.  You may or may not have max or min at one or the other.

Mitch is buying candy bars for his friends. He wants to give 2 bars to each friend, and he wants to have 10 spare bars. He can a
gregori [183]

Answer:

A. 2f + 10 = 28

Step-by-step explanation:

28 candy bars.

He wants 10.

28 - 10.

18 candy bars.

He gives each friend 2.

18 divided by 2.

9.

He can treat 9 friends.

Step 1: Subtract 10 from both sides.

2f+10=28

which would take away the 10 and subtract 10 from 28. (That would be Jack's bars.)

2f = 28.

Step 2: Divide by 2 on both sides.

2f = 28

which would cancel out the 2f. And Whatever is done to the left is done to the right, meaning you would divide 28 by 2 aswell. (Dividing up the candy bars among his friends).

f = 9

Rewrite in a form that does not use exponents
emmainna [20.7K]

Answer:

  \boxed{18}

Step-by-step explanation:

One of the rules of logarithms is ...

  log(a^b) = b·log(a)

So ...

6\log_5{x^3}=6(3\log_5{x})=\bf{18}\log_5{x}

Erin writes the expression “ $6$ less than double a number.”
bixtya [17]

For this case we must algebraically rewrite the given expression. So:

x: It is the variable that represents an unknown number

"double a number" is represented as: 2x

"6 less than double a number" is represented as: 2x-6

So, the final expression is: 2x-6

If we want to rewrite the expression in an equivalent way, we take common factor 2:

2 (x-3)

Asnwer:

2x-6

Equivalent expression: 2 (x-3)
