Tina is considering two cell phone plans and wishes to decide, based on her expected phone usage,
which plan to purchase. Plan A has a monthly fee of $4995. Plan B costs $39.95 per month. Plan A
charges 5¢ per minute after 300 minutes of talk time. Plan B charges 10€ per minute for any talk time
beyond 500 minutes. Which pair of equations could Tina use to decide on the least costly plan for her
usage? Assume Tina always uses more than 500 minutes per month
(a) c = 39.95 + 0,10m - 300)
(b) c = 39.95 + 0.1(m - 500)
c = 49.95 + 0.050m - 500)
C = 49.95 + 0.05(m - 300)
(c) =3995+0.11 - 50
(d) =3995 +0.11 - 500
C = 49.95 + 0.05m - 15
c = 49.95 + 0.05m - 300

In math formulas, A and a, always represent the same number.

Answers

Answer:  False

Step-by-step explanation:

In math formulas, we want to use different symbols to represent different things.

While in linguistics, A and a represent the same thing, the symbols are different, then we can use them to represent different things.

For example, we can define a square of side length a.

And the area of that square will be equal to the square of its side length, we can represent the area with A, such that:

A = a^2.

Here A and a are different numbers (and also represent different measures, a is in units of length and A is in units of surface).

Then the statement is false.

Simplify your answer.​

Answers

Answer:

[tex]\frac{4}{25}[/tex]

Step-by-step explanation:

Given expression:

          [tex]-\frac{1s }{20r}[/tex]  

   r  = [tex]-\frac{1}{4}[/tex] , s = [tex]\frac{4}{5}[/tex]

Now;

     [tex]-\frac{1s }{20r}[/tex]    = [tex]-\frac{s}{20r}[/tex]

              Insert the parameters:

                = [tex]-\frac{\frac{4}{5} }{20 x (-\frac{1}{4} )}[/tex]  

               = - [tex]\frac{\frac{4}{5} }{-5}[/tex]  

              -x - = +

                = [tex]\frac{4}{5}[/tex] x [tex]\frac{1}{5}[/tex]

                = [tex]\frac{4}{25}[/tex]

Answers

Answer:

1st box: 2

2nd box: 5

3rd box: 8

4th box: 11

5th box: 14

Step-by-step explanation: Plug in the formula y=3x+5. For example, you plug -1 as x, and you get y=(3)(-1)+5. 3 x -1 is -3, and then you add 5. The final answer is 2. Just do the same thing on the other boxes. Use the x values and plug it in into the formula shown.

All you have to do to find y is plug in the values of x given in the chart and onto the equation

1st: x = -1
y = 3x + 5
y = 3(-1) + 5
y = -3 + 5
y = 2

(-1, 2)

2nd: x = 0
y = 3x + 5
y = 3(0) + 5
y = 0 + 5
y = 5

(0,5)

3rd: x = 1 y= 8

4th: x = 2 y= 11

5th: x = 3 y= 14

Which of the following
represents a function?
PLEASE HELP 15 POINTS OR BRAINLIEST JUST ASK PLEASE HELP ME

Answers

Answer:

A: represents a function

Explanation:

Every other option, A,  has two y for one x.

It can be a function if there is 1x for 1y.

If this was helpful, please mark brainliest. Have a beautiful day!

Answer: Choice C (upper right corner)

Choice A is not a function because x = 2 leads to more than one y value (y = 1 and y = 7  at the same time)

Choice B is not a function for similar reasoning. Here we have x = 1 lead to y = 2 and y = 5 simultaneously.

Choice D is also not a function because of the two points (5,2) and (5,4). This tells us we have x =  5 lead to y = 2 and y = 4 at the same time.

A function is only possible if you have any input lead to exactly one output. Choice C shows this. Note how it passes the vertical line test. It is impossible to draw a vertical line through more than two points on the function curve.
