3)
f(x) =(x+1)/4
so
f(6a) = (6a+1) / 4
f(6a) =3/2(a) + 1/4

8)
f(x) =(x+1)/4 = 0
x + 1 =0
x = -1

answer
x = -1 makes f(x) = 0

9)
(x+1)/4 >= 10
x + 1 >= 40
x >= 39

Answer
Domain is any number greater or equal 39 (x >= 39)

Ben has a cell phone plan that provides 200 free minutes each month for a

user100 [1]

Answer:

The piecewise functions accurately represents charges based on Ben's cell phone plan is :

$f(x)= 39, x \leq 200\\f(x)=39 + 0.35(x - 200), x > 200}$

Step-by-step explanation:

Let x be the minutes over cell phone

Let f(x) represents the piecewise function that represents the charges based on Ben's cell phone plan.

We are given that Ben has a cell phone plan that provides 200 free minutes each month for a flat rate of $39.

So, $f(x)= 39, x \leq 200$

We are also given that For any minutes over 200, Ben is charged $0.35 per minute.

So, Minutes over 200 = x-200

$f(x)=39 + 0.35(x - 200), x > 200}$

Hence the piecewise functions accurately represents charges based on Ben's cell phone plan is :

$f(x)= 39, x \leq 200\\f(x)=39 + 0.35(x - 200), x > 200}$

Samuel makes a dozen of mini cupcakes using 5/8 cups of sugar, 3 cups of chocolate chips and 1/2 cup of butter. If each cupcak

baherus [9]

I don't what form of measurement to use (like grams, cusp, etc.) but I'm pretty sure it'd be cups

I think it's 5/96 or .05208333

So, 5/8 is .625. Dividing that up in throwing it into 12 cupcakes.

Solve the inequality: -6n - 12 >= 3(-n + 12)

Verizon [17]

Answer:

-16 > n or n < -16

Step-by-step explanation:

First, we can write the inequality and distribute.

-6n-12 > 3(-n+12)

-6n-12 > -3n+36

Get rid of a variable first (it makes solving a lot easier). We can add 6n to both sides.

-6n-12 > -3n+36

+6n +6n

-12 > 3n+36

Now, we can subtract 36 on both sides.

-12 > 3n+36

-36 -36

-48 > 3n

Divide by 3 on both sides.

-48 > 3n

/3 /3

-16 > n or (if it's easier) n < -16

Hope this helps!! Have a wonderful day C:
